What Is TPEE Polymer

As applications in consumer electronics, automotive parts, industrial hoses, and other fields place higher demands on the performance of elastomer materials, TPEE (thermoplastic polyester elastomer), with its excellent heat resistance and mechanical strength, has become a key bridge between engineering plastics and rubber. SK Global Chemical's TPEE LP380A, a high-performance TPEE polymer, represents a mid-to-high-end elastomer for diverse applications. It performs outstandingly in processing adaptability, structural stability and heat resistance grade, bringing more possibilities to injection molding and extrusion applications.

01 | Material Highlights and Characteristics: A Model of Balanced Performance

The main characteristics of TPEE Polymer LP380A include:

✅ High elasticity and high strength combined: stable tensile performance at different strain levels;

✅ Excellent tensile resilience: elongation at break as high as 1400%, with excellent flexibility;

✅ Moderate resistance to compression deformation: In medium-temperature applications (such as 70°C), it has a certain degree of compressive durability and is suitable for scenarios with moderate compression recovery requirements;

✅ Good thermal stability: melting point up to 179°C; Maintain the structure from deforming in high-temperature molding or working environments;

✅ High processing efficiency: high melt index, suitable for injection molding and extrusion dual-mode molding;

✅ Strong dimensional stability and medium moisture absorption: Although it has a certain water absorption rate (0.9%), short-term use has a relatively small impact on the structure. It is recommended to avoid continuous high-humidity environments.
