TPEE
TPEE (thermoplastic polyester elastomer) is a block copolymer containing polyester hard segments and polyether soft segments. The polyether soft segment and the uncrystallized polyester form an amorphous phase and the polyester hard segment is partially crystallized to form a crystalline microdomain, which acts as a physical cross-linking point. TPEE has the elasticity of rubber and the strength of engineering plastics; the soft segment gives it elasticity, making it like rubber; the hard segment gives it processability, making it like plastic; compared with rubber, it has better processability and longer. Service life; compared with engineering plastics, it also has the characteristics of high strength, and better flexibility and dynamic mechanical properties.
Application:
TPEE is mainly used in fields that require shock absorption, impact resistance, flex resistance, sealing and elasticity, oil resistance, chemical resistance and sufficient strength. Such as: polymer modification, auto parts, high and low temperature resistant wire sheath, hydraulic hose, shoe material, transmission belt, rotary molding tire, flexible coupling, muffler gear, elevator slide, chemical equipment pipeline valve Anti-corrosion, wear-resistant, high- and low-temperature resistant materials, etc.
