What is Keyflex BT 1055D

In industries such as automobiles and sports equipment, material selection is no longer confined to merely "meeting basic functions", but rather requires a balance to be struck among performance, processing convenience and environmental sustainability. Keyflex BT 1055D, launched by LG Engineering Plastics, is a TPC-ET (thermoplastic polyester elastomer) that offers stable performance in a variety of application scenarios. It combines flexibility, heat resistance and dimensional stability, providing a broader range of choices for design and production.

01 | Main performance characteristics

Combining hardness with flexibility

  ・While maintaining moderate rigidity, the Keyflex BT 1055D retains excellent resilience and flexibility, ensuring long-term stability under continuous bending and impact conditions.

Strong low-temperature impact resistance

  ・Even in an environment of -40°C, it can maintain excellent impact resistance and is suitable for automotive exterior parts and outdoor sports equipment in cold regions.

Good thermal stability

  ・The melting temperature can reach 205°C, and the heat distortion temperature is stable. It is not prone to deformation during processing and use.

High dimensional accuracy

  ・It has a low shrinkage rate and is suitable for complex components with high dimensional accuracy requirements, reducing assembly errors.

02 | Typical applications of Keyflex BT 1055D

The automotive field

  ・Flexible connectors, wire harness sheaths, sealing rings, guiding parts, etc., have both weather resistance and impact resistance.

Sports and leisure products

  ・Skis support components, sports equipment buffer assemblies, fitness equipment protective cases, etc., enhance the comfort and safety of use.

Industry and household appliances

  ・The connecting parts, shock-absorbing parts, protective sleeves and other components can extend the service life of the equipment and enhance safety.

03 | Processing and technology compatibility

Keyflex BT 1055D is suitable for injection molding and extrusion molding:
