TPE (Thermoplastic Polyester Elastomer) is a block copolymer containing polyester hard segments and polyether soft segments.
Wherein the polyether soft segment and the non-crystalline polyester form the amorphous phase, the hard segment of the polyester partially crystallizes to form a crystalline micro-zone, which serves as a physical crosslinking point.
TPE has the elasticity of rubber and the strength of engineering plastic; the soft segment gives it elasticity so that it behaves
like rubber; the hard segment gives it processability making it like plastic, and it has better processability and longer Life;
compared with the engineering materials, the same high strength characteristics, and flexibility and dynamic mechanical properties
better.
TPE (thermoplastic elastomer) is a new type of polymer material between traditional rubber and plastic. It combines the high elasticity of rubber and the plasticity of plastic, and can be softened by heating, formed and cured by cooling within a certain temperature range. TPE is mainly composed of olefin plastics (such as polypropylene), elastomers (such as styrene butadiene rubber) and necessary additives, and has excellent properties such as aging resistance, oil resistance, wear resistance and weather resistance. TPE material does not need vulcanization or vulcanization time is short, has the characteristics of short processing cycle, can be recycled, is conducive to energy saving and environmental protection. It can be processed by general plastic forming machine, and is used in the manufacture of rubber shoes, sports equipment, high-grade toys, suction cup materials, sealing rings and industrial supplies.
