TPE (ThermoplasticElastomer) is a kind of thermoplastic elastomer material, which has the characteristics of high strength, high resilience and injection molding. It has a wide range of applications, environmental protection, non-toxic and safe, and excellent coloring property. 1. TPE Styrene TPE, also known as TPS, is a block copolymer of butadiene or isopentadiene and styrene, whose properties are closest to SBR rubber. At present, the world production of TPS has reached more than 700,000 t, accounting for about half of the total TPE. The representative variety is styrene butadiene styrene block copolymer (SBS), widely used in footwear industry, has mostly replaced rubber; At the same time in the rubber cloth, rubber plate and other industrial rubber products in the use is also expanding. SBS is also widely used as an impact modifier for PS plastics, and it is also an excellent modifier for wear resistance, crack resistance, soft resistance and skid resistance of asphalt pavement. PS modified with SBS not only greatly improves impact resistance like rubber, but also has excellent transparency.

The asphalt pavement modified by SBS is more easily dissolved in asphalt than SBR rubber and WRP rubber powder. Therefore, although the price is more expensive, it is still widely used. Nowadays, more waterproof coil is further promoted to the roof of the building, subway, tunnel, trench and other waterproof, moisture-proof above. The sponge made of SBS, S-SBR and NP rubber is more rubber tactile than the original PVC and EVA plastic sponge, and lighter than vulcanized rubber, with bright colors and clear patterns. Therefore, not only suitable for the manufacture of rubber shoes in the sole of the sponge, but also travel shoes, sports shoes, fashion shoes disposable outsole ideal material.
