A product developed with aramid fiber and high-quality imported graphite as the main material. Aramid fiber has high tensile strength, high tensile modulus, low density, excellent energy absorption and shock absorption, wear resistance, resistance to Fatigue, dimensional stability and other excellent mechanical properties, good chemical corrosion resistance, high heat resistance, low expansion, low thermal conductivity, non-combustible, non-melting and other outstanding thermal properties and excellent dielectric properties, this material and high carbon expanded graphite The combination of our products makes our products higher in strength, better in wear resistance, and more stable in friction coefficient. At the same time, it also reduces the density of the products and enhances the comfort of the use of the products. It is suitable for vehicles on various roads.
