TPEE (Thermoplastic Polyester Elastomer)

Thermoplastic Polyester Elastomer, TPEE, is high performance, high temperature material that has many features of thermoset rubber and the strength of engineering plastics. It is a block copolymer containing a hard segment of polyester and a soft segment of polyether. The hard segment offers the processing properties like plastic while the soft segment gives it with the flexibility. It possesses numerous excellent features and is commonly used in electrical appliances, IT, and automotive industries.

  • Outstanding Wear & Tear Resistance
  • High Impact Resistance
  • Excellent Flex Fatigue
  • Good Chemical & Heat Resistance
