Shan tensile strength is high, elongation is small (3%). Shan has high elasticity coefficient and good rigidity. In the Shan elastic limit, the elongation is large and the tensile strength is high, so the energy of absorbing shock is great. Shan is inorganic fiber, with non-flammable, good chemical resistance. Shan water absorption is small. Shan scale stability, heat resistance is good. Shan processing is good, can be made into strands, bundles, blankets, weaving and other different forms of products. Shan Transparent to light. The development of surface treatment agent with good Shan and resin is completed. Shan prices are cheap.
