Para Aramid Filament

100% Para Aramid filament yarn for military and civil use

Aramid filament mainly includes conventional, high-strength, high-modulus and high-elongation products. Because of its excellent strength, low density, good flame retardancy and thermal stability, it is widely used in communication optical cables, bulletproof and explosion-proof , aerospace, rail transit, high temperature protection and friction sealing and other fields.

Kevlar Filament

Aramid fiber is short for “aromatic polyamide fiber”. It is a new type of high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, high acid and alkali resistance and light weight. The fiber’s strength is 5 to 6 times of steel wires while the modulus is 2 to 3 times of steel wire or glass fiber. Furthermore, the toughness is double compared with the steel wire. But in terms of the weight, it takes only 1/5 of that of the steel wire. It can be used at a high temperature of 300°C for a long time. When the temperature reaches 450°C, it will begin to carbonize.

Filament is made of PPTA polymer. It presents high performance in various production processes due to its competitive and excellent properties in strength, weight and durability.

Filament also possesses of low flammability and excellent thermal stability, enabling its mechanical strength decay within 20% under 200°C, which is important in heat protection, friction and sealing fields.

To meet varied requirements of manufacturers, we provide complete and customized solution by applying wide range of linear densities and yarn counts, also available in different colors.
