What Is Thermoplastic Polyester Elastomer TPEE

At present, when flexible materials are increasingly valued by the manufacturing industry, thermoplastic polyester elastomer tpee is rapidly becoming a bridge between traditional rubber and engineering plastics. It not only possesses the processing efficiency of thermoplastic materials but also retains the durability and flexibility of elastomers. As a technical representative in this field, SK Comprehensive Chemical's TPEE G155D is standing out in the industrial field with its balanced performance.

01 | Material properties: Balancing strength, ductility and thermal stability

G155D is a structure-level option in the thermoplastic polyester elastomer tpee material system. Its core performance advantages are reflected in:

  ・Outstanding structural support: The material itself has good tensile and bending strength, making it suitable for functional components with requirements for rigidity and load-bearing capacity.

  ・Moderate ductility: The breaking elongation capacity reserves a certain anti-deformation space for flexible application scenarios, taking into account the balance between rigidity and flexibility.

  ・Strong thermal stability: Supported by a melting temperature of over 200°C, it is suitable for stable processing at medium and high temperatures, reducing processing stress and shrinkage deformation.

  ・Strong tear resistance: It is less likely to be cracked or torn at the corners in the structural design, making it suitable for key positions such as connectors, fasteners, and flexible accessories.

02 | Application fields: Multi-scenario solutions for industry and consumption

The typical applications of thermoplastic polyester elastomer TPEE G155D are widely distributed in the following fields:

  ・Automotive structural components and connecting elements: such as flexible clips in the engine compartment, hot zone connection covers, rigid-flex composite parts, etc.

  ・Wire and cable sheath: While maintaining structural hardness, it ensures resistance to bending and tensile cracking.

  ・Sports equipment and wearable components: used for sports fasteners, plug flexible connections, etc., taking into account both durability and elastic hand feel;

  ・Industrial machinery parts: such as soft gear covers, flexible slide rail assemblies, etc., where structural protection and mechanical wear resistance coexist.

04 | Process adaptability: Bidirectional compatibility with extrusion and injection molding

The thermoplastic polyester elastomer TPEE G155D supports mainstream injection molding and extrusion molding process routes and is particularly suitable for the following types of molding requirements:

  ・Continuous extrusion at high die temperature: Suitable for continuous profiles such as cable conduits and structural pipes;

  ・Injection molding with multi-stage temperature zone control: Strong thermal stability, wide processing window, suitable for complex mold cavities and pin insertion products;

  ・Stable molding efficiency: With a moderate melt index, it can improve the molding flow efficiency while still maintaining good surface quality and dimensional control.

05 | Industry advantage: Focusing on the selection of materials that are durable and structurally stable

Compared with other TPEE materials, G155D is more suitable for the following scenarios:

  ・Applications that have requirements for material rigidity and dimensional accuracy;

  ・High reliability requirements in long-cycle mechanical fatigue or dynamic stress scenarios;

  ・Industrial applications that require moderate resilience but emphasize structural safety;

  ・Manufacturers who pay attention to thermal stability, cavity filling and consistency of the workpiece during the molding process.

06 | Market feedback and reasons for recommendation

In actual applications by customers, G155D is often selected as an upgrade or replacement for the following materials:

Replace some soft engineering plastics, such as medium-hardness TPU, to enhance structural strength;

Replace some softer TPEE or TPE materials to increase service life while ensuring elasticity.

When co-injection molded with materials such as PA6 and PP, it serves as an elastic connection area to achieve a soft-hard composite structure.
