Preoxidized PAN Fiber Mat

 

Preoxidized fiber or preoxidized yarn is obtained by high-temperature heat stabilization treatment with polyacrylonitrile as raw material.

It has high flame retardancy, limiting oxygen index greater than 45%, excellent thermal stability, fiber does not melt, soften and shrink, no droplets during combustion, and is a quasi-non-flammable product; good thermal insulation effect, acid and alkali corrosion resistance, chemical environment resistance, and radiation resistance; suitable textile processing performance, light fabric, softness, good water absorption and other advantages.

 

Polyacrylonitrile raw silk is treated at 250-2800C to obtain preoxidized fiber made of felt, its thickness is 3-15mm, for people and objects that need to stay away from heat sources, it is an ideal and effective outer protective layer, preoxidized fiber flame retardant and high temperature resistant cloth, and it is very easy to wrap objects with uneven surfaces.

Preoxidized fiber felt can work for a long time at a high temperature of 220 degrees without aging, shrinking, and high temperature resistance of 1000 degrees without burning.

 

Application Areas:

Preoxidized fiber felt has good flame retardant, heat insulation and sound insulation properties. It can be widely used in car engine compartment, door sound insulation, car carpet, roof, trunk blanket, car seat inner covering, fire escape blanket.

High-speed train body sound insulation, and can be used for ships, passenger ships, hotels, etc., pads, bed sheets, curtains, stage curtains and furniture.

In addition, it also has excellent performance in high-temperature gas/solid filter materials, building flame retardant sound insulation and thermal insulation in high-temperature environments.
