thermoplastic elastomer is a cross between rubber and thermoplastic properties of polymer materials, has dual nature and broad characteristics of rubber and plastic, are widely used in automotive, electrical and electronic, construction and other fields, replacing traditional rubber products in many fields, the industrialized production of TPE is mainly divided into the following categories: styrene, vinyl chloride, polyester, etc.


styrene class class TPE for styrene butadiene and styrene block copolymer, the main varieties for SBS, the current domestic production capacity of about 220000, SBS have good tensile strength and projectile, friction resistance and fatigue performance is excellent, and cheap and fine, mainly used in rubber shoes, modified asphalt, synthetic resin modifying agent and adhesive, etc. , of which about 80% consumption for shoe industry.

PP foam in car manufacturing industry can be used as insurance side guard plate, cushion, sun visor, tool box, etc. As the packaging material can be used for fragile goods and the packing of the shockproof precision instruments, in the turbulence of the transit from damage and destruction. As a safety protection material can be used in all kinds of safety helmets. It also can be used as heat preservation, sound insulation effect good construction materials used in construction industry.

the TPV as automotive sealing strip has been recognized by the industry, the advantages of high molecular weight of TPV due to good wear resistance, small friction coefficient, as auto glass guide groove seal extrusion materials, more joint Angle can be used as automobile rubber materials, water foaming spongy TPV has been successfully developed abroad.

as a result of TPO in applications involving nearly hundred kinds of automotive spare parts, auto parts have been used abroad TPO instead of rubber products. As a result of TPO in importance and good application prospect in automobile and electronic electrical, become one of the fastest growing. In the TPE

thermoplastic polyurethane elastomer with high strength, good toughness and wear resistance can have the opposite sex. There are many new concern, such as using nanometer metal oxides and inorganic salt as antistatic material preparation of antistatic polyurethane elastomer, high temperature resistant polyurethane elastomer, biodegradable polyurethane elastomer, high damping polyurethane elastomer, liquid crystal polyurethane elastomer and so on.

diene class TPE for natural rubber isomers, called the trans of natural rubber. Additional TPAE, TPF, silicone rubber make plastic elastomer, acrylate rubber thermoplastic elastomer also gradually development and industrialization, including TPAE to develop in the direction of engineering; The TPF to high-performance ultra-low permeability automobile fuel hose, etc. ; Acrylate rubber thermoplastic elastomer is mainly used in auto parts. TPE is now becoming widely replace the traditional rubber and some plastic products widely used and the prospects for development extremely the new material.
