What Is Thermoplastic Polyester Elastomer

In industrial environments where the requirements for material properties are increasingly strict, Thermoplastic Polyester Elastomer (TPEE), with its unique combination of physical properties, is gradually becoming an ideal solution for connecting "rigidity" and "flexibility". The TPEE G240D launched by SK Comprehensive Chemical, as an engineering-grade elastomer material targeting the mid-to-high-end market, has demonstrated strong competitiveness in multiple application fields with its excellent heat resistance, mechanical strength and processing adaptability.

TPEE G240D

01 | Material highlights: A dual balance of mechanical and thermal properties

TPEE G240D combines the high strength characteristics of rigid Polyester with the elastic advantages of flexible ether segments. As an outstanding thermoplastic polyester elastomer, it has the following key properties:

  ・Good heat resistance and strong thermal stability: It can maintain structural strength and dimensional stability in high-temperature environments, making it suitable for long-term use scenarios with high heat loads.

  ・Flexibility and strength coexist: high tensile strength, large elongation at break, suitable for complex stress fields or repeated deformation conditions.

  ・Excellent fatigue resistance and creep resistance: Even under long-term force or dynamic cycling, it still maintains its original form and mechanical properties.

  ・Superior low-temperature flexibility: Even in cold environments, it still maintains high toughness and elasticity.

  ・Stable color and good consistency in appearance: It meets the long-term requirements for color retention of appearance parts and consumer goods.

These comprehensive properties make TPEE G240D one of the ideal materials that balance functionality and formability.

02 | Typical applications: Covering multiple key industrial fields

TPEE G240D has good adaptability and is widely used in the following fields:

  ・Automotive industry: It is used for components with high requirements for temperature resistance and fatigue resistance, such as pipe sheaths, elastic clamps, heat-resistant sealing strips, and wire harness coverings.

  ・Electronic and electrical: Particularly suitable for cable sheaths and connecting parts covering, providing excellent insulation, fire resistance and wear resistance performance.

  ・Pipe and film extrusion: Maintains structural stability in continuous bending and pressure resistance scenarios, suitable for industrial pipelines and protective film materials.

  ・Composite material substrate: It can be co-extruded or coated with various engineering plastics to enhance the comprehensive performance of the finished product.

The wide application basis of thermoplastic polyester elastomer enables it to have strong expansion space in both emerging and traditional manufacturing industries.
