TPEE, or Thermoplastic Polyester Elastomer, is a block copolymer composed of polyester hard segments and polyether soft segments. It combines the elasticity of rubber with the strength of engineering plastics, with core characteristics including excellent resilience and fatigue resistance, along with outstanding performance in heat resistance, chemical resistance, and mechanical properties. TPEE is often used as a modifier for various plastics and rubbers, and it is widely applied in automotive components, hydraulic hoses, industrial gears, sports equipment, and other fields requiring high dynamic performance.
