There are several types of fibers that are known for their flame retardant properties. Some examples include:
Nomex: This is a brand of flame-resistant fiber developed by DuPont. It is made from aramid, a synthetic polymer with high strength and heat resistance. Nomex is commonly used in protective clothing for firefighters, as well as in aircraft and military applications.
Kevlar: This is another brand of aramid fiber developed by DuPont. It is known for its high tensile strength and ability to withstand heat and flame. Kevlar is often used in bulletproof vests and other types of personal protective equipment.
FR-7: This is a flame-resistant fiber developed by the Japanese company Teijin. It is made from a blend of cellulose and a synthetic polymer, and it is known for its high strength and flame resistance. FR-7 is commonly used in protective clothing and other applications where flame resistance is important.
PBI: This is a brand of flame-resistant fiber developed by the company Milliken. It is made from a synthetic polymer called polybenzimidazole, and it is known for its high strength and flame resistance. PBI is often used in protective clothing and other applications where flame resistance is important.
Modacrylic: This is a type of synthetic fiber made from a modified acrylic polymer. It is known for its flame-resistant properties and is often used in protective clothing and other applications where flame resistance is important.
Viscose: This is a type of cellulosic fiber made from plant-based materials, such as wood pulp or bamboo. Some viscose fibers are treated with flame-resistant chemicals to improve their flame resistance.
Wool: Natural wool fibers have some inherent flame-resistant properties, although they are not as flame-resistant as some synthetic fibers. Wool fibers can be treated with flame-resistant chemicals to improve their flame resistance.
Cotton: Natural cotton fibers have some inherent flame-resistant properties, although they are not as flame-resistant as some synthetic fibers. Cotton fibers can be treated with flame-resistant chemicals to improve their flame resistance.
It is worth noting that no fiber is completely flame-proof, and the effectiveness of a flame-resistant fiber will depend on the specific application and the conditions it is exposed to
