Para Aramid Fiber
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
Para Aramid Paper
Since the specific strength and specific modulus of para-aramid are 6 times and 3 times that of steel wire, and 2 times and 10 times that of high strength nylon, they can maintain normal levels in the temperature range of -200 ℃-200℃ . Under the premise of the same tensile strength, the para-aramid skeleton material can greatly reduce the quality of rubber products and can be used in extreme weather conditions. The para-aramid has excellent low creep, fatigue resistance, low heat shrinkage and chemical corrosion resistance, which can significantly improve the dimensional stability and service life of rubber products.
