Is Polyfill Flammable?

Polyfill is often used to fill the space inside a mattress or pad. It is different from paper and other traditional fillings. The use of polyfill often raises the question: Is polyfill flammable? I’ll break down all the myths surrounding polyfill and explain if it’s safe.

Polyfill is made from synthetic fibers such as polyester and polypropylene, which are used to make up the stuffing inside pillows. Polyfill has been known to catch fire when exposed to high heat levels, but this only happens in cases where it is burned or damaged.

However, Polyfills are not intended for use in mattress covers, pillow covers, or other types of bedding because these materials contain natural fibers such as cotton or wool that can be flammable if exposed to heat. Polyfill can be used in many ways:

1. It is put inside pockets to keep them from tearing or adds comfort when the wearer moves around a lot

2. It can be sewn into clothing to create padding

3. It is used as stuffing for pillows and mattresses.

What Is Poly Fill

Poly fill, also known as polyester fiberfill, is a synthetic fiber used for stuffing pillows, other soft objects, and for acoustic purposes. It is commonly sold under the trademark name Poly-Fil, or un-trademarked as polyfill.

Polyester fiberfill is made from a process called meltblown, which melts and then blows polyester resin into tiny fibers. These fibers are then heat-treated to create a soft, fluffy material. Polyfill is typically white or off-white in color, but it can also be dyed other colors.

Polyfill has a number of advantages over other stuffing materials, such as down and feathers. It is more durable and resists mold and mildew. It is also hypoallergenic, making it a good choice for people with allergies. Polyfill is also relatively inexpensive, making it a cost-effective stuffing material.

Polyfill is used in a variety of applications, including:

Pillows
Stuffed animals
Beanbags
Quilts
Mattresses
Acoustic panels
Clothing insulation
Stuffing for dolls and toys

Polyfill is a versatile and affordable stuffing material that is perfect for a variety of applications. It is durable, hypoallergenic, and relatively inexpensive. If you are looking for a stuffing material that will last, polyfill is a good choice.

Here are some additional things to know about poly fill:

It is typically sold in bags or rolls.
It can be machine washed and dried on low heat.
It is available in a variety of densities, so you can choose the right weight for your needs.
It is non-toxic and safe for children and pets.

Polyfill is made from polyester and used to replace cotton in many products, including bedding. It is a thin, soft fiber that is made from synthetic materials. It’s used to fill gaps and add volume to clothing, especially in garments’ shoulders, arms, and necklines. Polyfill is not flammable–it won’t catch fire when exposed to flames or sparks.

It’s a non-flammable material, safe to use in applications where you want a soft feel without creating a fire risk. However, it does burn and doesn’t burn like cotton or wool does when they’re exposed to flame. It does not produce much smoke when it burns, but it will still produce some. It means you can safely use polyfill in your home without worrying about it catching fire.

Polyfill is not considered a fire hazard when used for the purpose for which it was intended (as insulation or clothing). Still, if you are using it as a stuffing material for pillows or mattresses, you should avoid putting anything on top of your bed, including sheets that could get hot enough to set fire to the polyfill (or any plastics).

Is Polyfill Conductive?

Polyfill, also known as polyester fiberfill or simply fiberfill, is a synthetic material commonly used in the textile industry as stuffing or padding for various products such as pillows, stuffed animals, and jackets.

Polyfill itself is not inherently conductive, meaning it does not conduct electricity like metals or some other materials. However, some types of polyfill may contain conductive fibers or additives, which can give them some level of conductivity.

For example, certain types of conductive polyfill are used in the production of electromagnetic shielding materials, which are designed to block or reduce the amount of electromagnetic radiation that passes through them. These materials are often used in electronic devices, such as cell phones and computers, to prevent interference from other nearby electronic devices.

It is important to note that the conductivity of polyfill varies depending on the specific type and composition of the material, and it is not generally considered a conductive material in the same way that metals or other conductive materials are.

What Temperature Does Polyester Melt?

Polyester is an example of a polymer that can be melted and cast into different shapes, such as bottles and boxes used for food packaging. Polyethylene Terephthalate (PET) is another example of a plastic that can be melted and cast into different shapes.

It melts at about 300° C, but it does not burn. The melting point and decomposition point of polyester are the same. Polyester does not melt entirely at room temperature, but the melting process begins at temperatures above 150° C. If you put polyester in a heated oven or on a hot plate, it will melt, but it will still be visible as a solid material.

However, the melting point of polyester is higher than that of nylon and other synthetic fibers because it is a thermoplastic material, meaning it can be melted and reformed into its original shape.

What Is Polyfill Used for?

Polyfill is a type of fiberfill used to add volume to a product. It is usually an air-filled material that is made up of synthetic fibers. Polyfill can be added to items such as pillows, blankets, toys, and stuffed animals. Most brands of polyfill are produced from acrylics or polyester fibers.

Polyfill is used in a variety of industries and applications:

1. Polyfill is used in filling pillows and mattresses.

2. Polyfill can also be used for stuffed animal toys and other items.

3. Construction industries can also use polyfill, often added to the carpet padding or underlayment materials, to increase their comfort level. At the same time, they are installed or removed from floors or walls.

However, a polyfill is commonly sold in bulk bags or boxes. The product comes in a wide variety of colors and sizes so that it can be easily mixed with other materials when needed, usually made from polyurethane or polystyrene, which makes it light and flexible.

The main advantage of using polyfill is that it does not require any other materials besides itself. This means that the resulting product is lighter than its equivalent mass of cotton or wool stuffing, which can be challenging if you are trying to make a product with lots of volume.

Also, polyfill provides extra support for the product’s structure without adding weight or bulk, which can be helpful in some cases. For example, if you want your stuffed animals to have more form but don’t want to add bulky materials like cotton batting into your project, then polyfill can help with this problem.

How Flammable Is Poly Fill?

Polyfill is a synthetic fiber that is made from polypropylene. It’s used in many applications, including sleeping bags, mattresses, and pillows. Polyfill has a thin, tight weave that feels soft like cotton but is fire-resistant.

The flammability of polyester and polypropylene fill varies depending on the type and quality of the fabric used to make it. For example, some materials have low flame spread ratings (FPRs), while others have high FPRs.

However, the flammability ratings of polyester are typically between 1 and 2 on the BPI scale (sometimes even lower). Polyester is considered non-flammable

Polypropylene has an FPR between 3 and 5 on the BPI scale, depending on quality and grade. The higher the number, however, the less likely it is to burn if exposed to flame or heat source. Polyfill is a safe choice for fireworks displays or parties where guests are likely to be around open flames.

Alternatively, polyester fibers are made up of long chains of molecules called polymers. These chains are usually made from large molecules called monomers, which are connected via hydrogen bonds. These bonds can break when exposed to heat or flame, causing the polymer to melt and turn into a liquid or gas.

The main reason why polyester isn’t considered as flammable as other materials are that it’s so sensitive to heat and flame that it breaks down into smaller pieces very easily.

What Is Polyfill Made Of?

Polyfill fills gaps and adds warmth to sleeping bags, jackets, pillows, and more. It’s made from polyester or polyester blends, filled with fiberfill or polyester fiber. Polyfill can be used in any item that needs warmth or insulation, including sleeping bags, jackets, pillows, and much more.

Polyfill is made of polyester, which is a synthetic fiber. Polyester is a member of the polyamides family of fibers. Polyester is produced by polymerizing methylene bis-acrylamide (MBA) using the Stereospecific Diels-Alder reaction.

Nevertheless, polyfill comes in many different colors and even shapes. Some have a smooth surface, while others have a fuzzy texture. The type of polyfill you need depends on the application where it will be used.

In fact, polyester has many uses in clothing, textiles, and other products. Polyester is often used as reinforcing filler in plastics because it has good mechanical properties and can be easily molded into shapes.

What Is Polyfill Pillow

A polyfill pillow is filled with cotton, polyester, or other fiber. The fiber can provide support and comfort for the neck, head, and back. Some designers use polyfill pillows to create the feel of down pillows.

Down is a natural fiber from birds or animals. When used as a stuffing material in a down pillow, it provides more support and softness than regular cotton filler.

Although polyfill pillows come in many shapes and sizes, they are most commonly used in three ways:

1. Body Pillow – A body pillow is a type of pillow that is designed to be used around your waist area or lower back. They are usually made of foam and may have an armrest attached to the side to ease your arms on them while lying down on your side or stomach area. Body pillows can be filled with cotton but are usually filled with another type of material, such as foam.

2. Neck Pillow – Neck pillows are similar to body pillows, except they are not specifically designed for your waist or lower back area.

3. Back pillow – They are designed for the lower part of the back to relieve waist and back pain.

However, polyfill pillows are popular because they’re inexpensive, easy to use, and come in various shapes and sizes. There are also plenty of materials available for making your polyfill.

Can You Mix Ported and Sealed Subwoofers

Ported subwoofers are great for adding bass to your music, but they tend to sound boomier and less controlled. Sealed subwoofers are better at controlling the bass and keeping it tight, but they tend not to be as loud. You can mix them to get the best of both worlds.

The reason why you can mix ported and sealed subwoofers is that sealed subs do not have the same kind of porting as ported subwoofers. To understand why you need to know that porting is a way of taking pressure off a speaker’s voice coil to have more power.

This means you can get more bass from a sealed subwoofer because the voice coil will be less stressful. But, you must ensure they are correctly matched and in the proper location if you mix ported and sealed subwoofers.

However, the first thing to consider is the frequency range. A ported subwoofer has low frequencies that are very easy to produce, while a sealed subwoofer creates high frequencies. Ported subwoofers tend to have a higher output range than sealed subs, but they also have more room for air displacement.

Another difference between sealed and ported subs is their power-handling capabilities. A sealed sub will last longer than its ported counterpart because it is less likely to be damaged by excessive power levels.

Finally, there’s the issue of sound quality between the two subs. While you can mix them for better output, you’ll probably notice a loss in quality compared to using just one type or another.

Melting Temp of Polyester

A polymer is a molecule consisting of repeating units called monomers. Polymers are the primary raw materials used to produce plastics, fibers, and films. Polymers are generally characterized by their melting temperature and their glass transition temperature.

The melting temperature is the temperature at which a polymer loses its crystalline structure and becomes gaseous when it is heated to this point; the glass transition temperature is the temperature at which a polymer changes from a solid to a semi-liquid or liquid state. The melting temperature of polyester is between 285 and 315°C, or 538 and 575°F.

However, in its simplest form, polyester is an artificial material derived from petroleum, a non-flammable and highly durable material that can be used for many different applications. It’s commonly used in clothing and textiles because of its softness, durability, and resistance to water.

Is Polyfill Safe?

Polyfill is a type of insulation that can be used in place of natural materials like wool, feathers, or down. It’s easy to dress up your home and make it feel more luxurious.

Polyfill can be safe if used in a well-ventilated area because it’s not as toxic as some other fibers. However, it does have a high concentration of carbon dioxide gas, which causes fatigue and stress on the body.

Exposure to high concentrations of this gas for extended periods (such as during a construction project) can be dangerous for your health.

Fortunately, there are ways to reduce the adverse effects on your health by using safer polyfills. For example:

1. Use recycled polyfills instead of new ones when buying new furniture; this will reduce the number of toxic chemicals in use and simultaneously make your home more environmentally friendly.

2. Look for organic polyfills if you’re concerned about any potential health problems caused by toxic chemicals in your home environment.

However, when buying polyfill, ensure the material is 100% polyester or a blend of polyester and cotton. These materials are safe for you because they won’t release harmful chemicals into your body when you wear them.

Is Polyfill Toxic?

Polyfill is a type of foam made out of polyester. It is often used in cushioning materials, toys, and other products and also insulates well. Polyfill is not harmful to humans or pets when consumed by itself.

However, it can be harmful if it is ingested by a child or pet and causes problems like choking or vomiting. However, it’s not entirely natural. It contains toxic chemicals linked to cancer, hormone disruption, etc.

While polyfill has some benefits over other materials for making upholstery padding for furniture, it’s not always safe for human use. For example, some polyfills are known to cause allergic reactions in some people.

There are things to do to ensure that you’re not putting yourself at risk if you’re using polyfill in your knitting:

1. Make sure you’re using the correct type of polyfill. Different kinds of polyfills have other properties, so make sure your item doesn’t end up with holes because it’s not supported correctly by the yarn.

2. Use enough polyfill. Even if you want to use less than what’s recommended for specific project sizes, don’t skimp on this crucial ingredient; make sure you have a little extra so that when there are mistakes or breaks in the yarn, there’ll still be enough support for your project.

3. If you notice any itching or irritation after using polyfill (or any other product), stop using that item immediately.

Does Polyfill Make a Difference?

Polyfill is used to fill the open spaces between layers of fabric, such as when using batting or fleece in quilting. Using polyfill can reduce the amount of batting and fleece needed for projects, which helps reduce waste and cost.

Also polyfill can also help your projects last longer by making a softer, more comfortable fabric. It can also help add structure to the material by preventing it from sagging and keeping it straight while you work on it.

Additionally, a polyfill is excellent for ensuring you have enough thickness in your garment when sewing it together, it gives more structure to your attire so that it won’t be so floppy. If you’re making something like a shirt or skirt and want to ensure it doesn’t get too big around the waist or hips, polyfill can help,

When choosing which size of polyfill to buy, consider how wide it needs to be cut. If you’re using a rotary cutter or scissors with an adjustable blade width, choose one slightly smaller than your fabric’s width (but not so small that it won’t work).

Furthermore, you’ll need extra fabric on either side of this narrow piece of material so that you can fold over the edges without them puckering up when you cut them later on down the line.

Is Polyfill Warm?

Polyfill is made of polyester fibers, usually a little warmer than wool, acrylic, or other natural fibers. It can be used to make warm and lightweight blankets so you don’t feel weighed down by a heavy blanket on your lap during a long flight or car ride.

Blankets made from polyfill are highly breathable, so they will not hold onto your sweat as much as other types of fabrics would if you wear them for an extended period. Polyfill is warm because it’s cozy and soft. It’s made of polyester, so it’s not as heavy as a wool sweater, but it keeps you warm on a chilly day.

Besides, the fabric keeps you warm without feeling stifling or sweaty. It has a slight sheen that adds an extra layer of warmth, making it feel luxurious while remaining lightweight. Polyfill also comes in various colors, giving you many options for coordinating your outfit with this material.

Is Poly Fil Toxic?

Polyfill is generally considered to be non-toxic. However, it is important to note that it is a petroleum-based product, and therefore it may contain some trace amounts of chemicals. These chemicals are not typically harmful in small amounts, but they can cause health problems if ingested or inhaled in large quantities.

The Material Safety Data Sheet (MSDS) for polyfill states that it can cause eye and skin irritation, and it may also cause respiratory problems if inhaled. The MSDS also states that polyfill is flammable and should not be exposed to open flames.

If you are concerned about the safety of polyfill, you can choose a polyfill that is specifically labeled as “hypoallergenic” or “organic.” These polyfills are typically made with less chemicals and are therefore considered to be safer for people with allergies or sensitivities.

Here are some tips for using polyfill safely:

Avoid inhaling polyfill dust. If you do inhale polyfill dust, it can cause respiratory problems.
Keep polyfill away from children and pets. If a child or pet ingests polyfill, it can cause stomach upset or diarrhea.
Do not expose polyfill to open flames. Polyfill is flammable and can catch fire.
Wash polyfill regularly to remove dust and dirt.

What Can I Use Instead of Polyfill?

Here are some alternative stuffing materials for pillows, stuffed animals, and other soft furnishings, without images:

Organic cotton stuffing: This is a natural and sustainable option that is soft and comfortable. It is also machine washable and hypoallergenic.
Wool stuffing: Wool is another natural material that is soft and warm. It is also fire-resistant and moisture-wicking.
Kapok: Kapok is a natural fiber that is harvested from the kapok tree. It is soft, light, and buoyant.
Down: Down is a soft and fluffy material that is made from the feathers of geese or ducks. It is very comfortable, but it can be expensive and not as durable as other options.
Feathers: Feathers are another option that is made from the feathers of geese or ducks. They are not as soft as down, but they are more durable and less expensive.
Recycled fluff: This is a stuffing material that is made from recycled textile waste. It is a sustainable option that is also soft and comfortable.
Plastic bags: This is an unconventional stuffing material, but it can be used if you are on a tight budget. Simply cut up plastic bags into small pieces and stuff them into your project.

When choosing a stuffing material, consider the following factors:

The weight of the stuffing: Heavier stuffing will provide more support, while lighter stuffing will be more comfortable.
The softness of the stuffing: Some stuffing materials are softer than others. Choose a material that is soft enough for your needs.
The durability of the stuffing: Some stuffing materials are more durable than others. Choose a material that will last for the life of your project.
The price of the stuffing: Stuffing materials can range in price from very affordable to very expensive. Choose a material that fits your budget.

What Is Polyfill Material?

Polyfill is a synthetic stuffing material made from polyester fibers. It is often used in pillows, stuffed animals, and other soft furnishings. Polyfill is soft, lightweight, and durable. It is also relatively inexpensive, making it a popular choice for many applications.

Polyfill is made by melting polyester resin and then forcing it through tiny holes, creating long, thin fibers. These fibers are then cut to a desired length and blended together to create the desired consistency. Polyfill can be made in a variety of densities, from lightweight and fluffy to dense and supportive.

Polyfill is a versatile material that can be used in a variety of ways. It is often used as a stuffing material for pillows, stuffed animals, and other soft furnishings. It can also be used as an insulator in clothing and bedding. Polyfill is also used in some medical applications, such as wound dressings and surgical implants.

Here are some of the advantages of using polyfill:

Soft and comfortable
Lightweight and durable
Relatively inexpensive
Versatile
Easy to clean

Here are some of the disadvantages of using polyfill:

Not as breathable as natural materials
Can be flammable
Can emit VOCs (volatile organic compounds)

Is Poly Fil Flame Retardant?

Polyfill is not inherently flame retardant. However, it can be treated with flame retardants to make it more resistant to fire. Flame retardants are chemicals that are added to materials to make them less flammable. They work by interfering with the combustion process.

There are a number of different flame retardants that can be used on polyfill. Some of the most common flame retardants include:

Brominated flame retardants (BFRs): BFRs are a type of flame retardant that contains bromine. They are effective at preventing fires, but they have been linked to health problems, such as cancer and reproductive problems.
Chlorinated flame retardants (CFRs): CFRs are a type of flame retardant that contains chlorine. They are also effective at preventing fires, but they have also been linked to health problems.
Organophosphate flame retardants (OPFRs): OPFRs are a type of flame retardant that contains phosphorus. They are less effective than BFRs and CFRs, but they are considered to be less harmful to human health.

The type of flame retardant that is used on polyfill will depend on the intended application. For example, polyfill that is used in children’s toys is typically treated with a flame retardant that is considered to be less harmful to human health.

It is important to note that even treated polyfill is not 100% flame retardant. It will still burn if it is exposed to a high enough heat source. However, flame retardants can help to slow the spread of fire and prevent the material from igniting in the first place.

If you are concerned about the flammability of polyfill, you can choose a product that is treated with a flame retardant. You can also purchase polyfill that is made from natural materials, such as cotton or wool. These materials are naturally flame retardant and do not require the use of chemicals.

Down Blend Fill Vs Polyfill

Down blend fill and polyfill are both stuffing materials that are commonly used in pillows, stuffed animals, and other soft furnishings. They have different properties and advantages, so the best choice for you will depend on your specific needs and preferences.

Down blend fill is a mixture of down and feathers. Down is the soft, fluffy undercoat of geese or ducks. It is very warm and comfortable, but it can be expensive. Feathers are the larger, stiffer outer feathers of geese or ducks. They are less expensive than down, but they are not as soft or comfortable.

Polyfill is a synthetic stuffing material made from polyester fibers. It is less expensive than down blend fill, but it is not as soft or warm. Polyfill is also not as breathable as down blend fill, which can make it feel warmer in hot weather.

Here is a table comparing the two materials:

Feature	Down Blend Fill	Polyfill
Cost	More expensive	Less expensive
Softness	Softer and more comfortable	Less soft and comfortable
Warmth	Warmer	Less warm
Breathability	More breathable	Less breathable
Durability	More durable	Less durable
Hypoallergenic	Can be hypoallergenic	Can be hypoallergenic
Machine washable	Yes	Yes

Here are some factors to consider when choosing between down blend fill and polyfill:

Budget: Down blend fill is more expensive than polyfill.
Comfort: Down blend fill is softer and more comfortable than polyfill.
Warmth: Down blend fill is warmer than polyfill.
Breathability: Down blend fill is more breathable than polyfill.
Durability: Down blend fill is more durable than polyfill.
Hypoallergenicity: Both down blend fill and polyfill can be hypoallergenic.
Machine washability: Both down blend fill and polyfill are machine washable.

If you are looking for the softest and most comfortable stuffing material, then down blend fill is the best choice. However, if you are on a budget or if you are looking for a stuffing material that is more breathable, then polyfill is a good option.

Is Polyester Flammable

Polyester is not inherently flammable. It has a flash point of 482 degrees Fahrenheit (250 degrees Celsius), which means that it will not ignite unless it is exposed to a flame or heat source at or above that temperature.

However, polyester will melt at a much lower temperature, around 220 degrees Fahrenheit (104 degrees Celsius). This means that if polyester does catch fire, it will melt and drip, which can cause additional fire hazards.

Polyester is often treated with flame retardants to make it less flammable. Flame retardants are chemicals that are added to materials to make them less likely to ignite or to spread fire. There are a number of different flame retardants that can be used on polyester, and the type of flame retardant that is used will depend on the intended application.

For example, polyester that is used in children’s clothing is typically treated with a flame retardant that is considered to be less harmful to human health. It is important to note that even treated polyester is not 100% flame retardant. It will still burn if it is exposed to a high enough heat source for a long enough time.

If you are concerned about the flammability of polyester, you can choose a product that is treated with a flame retardant. You can also purchase polyester that is made from recycled materials, as recycled polyester is often treated with flame retardants.

Here are some tips for reducing the flammability of polyester:

Avoid using polyester in areas where there is a risk of fire, such as near open flames or heat sources.
Choose polyester that is treated with a flame retardant.
Purchase polyester that is made from recycled materials.
Keep polyester clean and free of lint and other flammable materials.

Does Polyester Burn

Polyester can burn, but it is not as flammable as some other materials. It has a flash point of 482 degrees Fahrenheit (250 degrees Celsius), which means that it will not ignite unless it is exposed to a flame or heat source at or above that temperature.

What Is Polyfill Stuffing?

Polyfill stuffing is a fiber used to add volume or fill spaces in your products. It’s often used in pillows and mattresses, but it can also be used for other items like clothing.

The best polyfill stuffing for your product is made from 100% polyester and has a texture similar to cotton fiber. Polyfill stuffing is available in different colors, textures, sizes, and weights, so there’s something for everyone.

Polyfill stuffing has many benefits over other materials:

1. It can remarkably retain heat, so you can use it during winter without worrying about your product getting cold.

2. It’s very soft and pleasant against the skin

3. It has no smell or off-gassing smell like other fillers when exposed to air for too long (which means no nasty chemicals).

4. You can use this material anywhere because it’s washable. Polyfill stuffing is thinner than regular stuffing, which makes it great for stuffing pillows and cushions while still maintaining their shape; with polyfill stuffing, you can load your pillows without worrying about the material pilling or becoming too heavy.

Is 100% Polyester Fire Retardant?

Polyester is a kind of fiber, and it’s used in many different products, including clothing. It can be both fire-retardant and waterproof. This means that polyester will protect you from burns and keep your clothes dry when it gets wet.

This material is considered fire retardant because it can stop a fire from spreading across the fabric’s surface. Polyester resists heat and burning, preventing a fire from spreading to other materials in your home.

In addition to being made entirely of polyester, polyester fire retardants can be used on any fabric or material and come in many forms, such as liquid, powder, or additives that can be added to different kinds of cloth or products.

Polyfill Vs Cotton

Polyfill is a type of stuffing that is made with polyester fibers. It’s often used in pillows and stuffed animals because it provides softness and comfort. Polyfill is cheaper than cotton, so it’s more cost-effective if you need to buy a lot of it. However, polyfills are usually not as thick as cotton and don’t last long.

Cotton is another type of stuffing that helps make the filling inside pillows and stuffed animals soft, fluffy, and comfortable. Cotton is thicker than polyfill, so it will keep its shape after being loaded into something for an extended period. However, cotton may not be as durable as polyfill because it may be damaged by water or other liquids.

Furthermore, poly filters are usually less expensive than cotton because they’re made from synthetic materials; however, they’re not as durable or long-lasting as cotton when used in products like pillows or stuffed animals.

Polyester has better insulation properties than cotton but is often more expensive than other fabrics due to its high cost per yard or meter.

Conclusion

This article gives vivid clarity to “Is Polyfill Flammable.” Although polyfill is not a fuel source, nor is it particularly explosive if appropriately handled. It’s not a toxic substance classified as in-ignitable, meaning it can’t spread fire once ignited.

Make sure you store your polyfill in a safe place and keep it well away from any sources of ignition, to be on the safe side, just in case.
