TPEE is produced by 1.4-butanediol, polytetra-methylene glycol, and DMT or PTA going through copolymerization condensation. It also can be made into thermoplastic polyester elastomer composites through kneading procedure. TPEE possesses a number of excellent features and is widely used in electrical appliances, IT, and automotive industries.
Thermoplastic Polyester Elastomer (TPEE): Overview and Key Properties
| Category | Details |
|---|---|
| Chemical Structure | Block copolymer of hard (PBT) and soft (polyether/glycol) segments |
| Common Names | TPEE, TPC-ET, COPE (Copolyester Elastomer) |
| Key Features | Combines rubber-like elasticity with thermoplastic processability |
Physical & Mechanical Properties
| Property | Value/Range |

Comparison with Other Thermoplastic Elastomers
| Material | TPEE vs. Alternatives |
|---|---|
| TPU | Better heat resistance, lower abrasion |
| TPO | More flexible, lower cost |
| TPV | Superior chemical resistance, less elastic |
Market & Sustainability
| Aspect | Details |
|---|---|
| Global Market | ~$1.2 billion (2023), CAGR 5.5% (2024–2030) |
| Key Producers | DuPont (Hytrel®), DSM (Arnitel®), Toyobo (PELPRENE®) |
| Sustainability | Recyclable; bio-based variants under development |
Summary
TPEE excels in applications demanding elasticity, heat resistance, and mechanical durability. Its versatility spans automotive, industrial, and consumer sectors, though cost and hydrolysis sensitivity require careful material selection. Innovations focus on eco-friendly formulations and expanded medical uses.
