As a high-tech fiber featuring high strength, high modulus, low density and good wear resistance, Aramid is known as one of the world's four major high-tech fibers (carbon fiber, aramid fiber, high-strength high-modulus polyethylene fiber, basalt fiber). Para-aramid (PPTA), a country called aramid 1414

High strength - The tensile strength is 6 times that of steel wire

High modulus - The tensile modulus is 2-3 times that of steel wire and glass fiber; The density is only 1/5 of steel wire;

High temperature resistance -Thermal decomposition 550℃, long-term use at 220℃

Strong toughness - Soft without brittleness, strong impact resistance

Flame retardant - Good self-extinguishing, high oxygen index

Chemical resistance - Good corrosion resistance and rupture resistance

Chemical resistance - Good corrosion resistance and rupture resistance

Low thermal conductivity, small temperature coefficient, high dimensional stability and low density
