Preoxidized Fiber & Para Aramid Fiber Blended Fabric

Preoxidized fiber (Preoxidized Polyacrylonitrile fiber) is a new nonflammable fiber, with the technical data as below

limiting

oxygen index 55%-60%,

heat conductivity: 0.08~0.17J/(m·s·k),

elongation rate: 12~16%,

moisture absorption rate: 6%~10%,

strength: 1.6~2.3dN/tex,

initial modulus: 70~80dN/tex

It does not burn, melt, soften or drip, and can sustain 3 minutes in 900°C flames and will keep the original shape till carbonized. And it can be blended with other high temperature resistant high strength fibers, such as para aramid fiber, so as to have better high temp resistant and higher strength performances.

Para aramid is high-strength flame retardant fiber, usually used for bullet-proof fabric, the strength is as 5 times as steel.

This fabric made from these 2 fibers is the best fire retardant fabric, which can withstand 3 minutes in fire, non-flammable, not melting, not hot-shrinking and not hot cracking, also used as arc protective fabric, ATPV=11cal/m2, anti-flash fire 20000°C.

High temperature resistant workwear,
Firefighting suit, gloves, socks,
Combat uniforms,
Welding clothing,
Flame retardant & heat-resistant curtains or covers,
Seat coats of automobile, train, airplane, etc.
