The Para-aramid filament is made of polycondensation of p-phenylenediamine and terephthaloyl chloride. The appearance of the filament is golden yellow, the relative density is low, and the strength is 5-6 times that of steel wire. It has good flame retardancy and thermal stability. It can maintain performance decay at 200OC.

The main specifications are 200D, 400D, 600D, 800D, 1000D,1500D, 3000D, which are widely used in tires, optical cables,hoses, rubber products, ropes, high-speed rail, personal protection, friction, sealing and other fields.
