Where Elasticity Meets Engineering Performance
TPEE (Thermoplastic Polyester Elastomer) is a high-performance thermoplastic elastomer developed for applications that demand both elasticity and mechanical strength. Its block copolymer structure combines hard polyester segments with soft segments, giving TPEE the resilience of rubber together with the strength, dimensional stability, and processing advantages of engineering plastics. This distinctive combination makes TPEE particularly suitable for components where flexibility cannot come at the expense of structural performance.
Designed to Endure Repeated Stress
TPEE stands out for its excellent flex fatigue resistance, toughness, impact strength, and resistance to creep and deformation. It also provides good resistance to oils, fuels, chemicals, and temperature variations, depending on the grade and service conditions. These properties allow TPEE to maintain its performance through repeated bending, mechanical loading, and long-term use, making it well suited to demanding operating environments.
Engineered for High-Performance Components
Prochase supplies TPEE materials for applications where conventional rubber or plastics may not provide the required balance of strength, elasticity, and durability. TPEE is used across automotive, electrical and electronics, industrial, consumer, and other engineering sectors, helping manufacturers develop components that require consistent mechanical performance, dimensional stability, and long service life.
- Exceptional Flex Fatigue Resistance: Designed to withstand repeated bending, flexing, and dynamic loading, TPEE maintains its elasticity and mechanical performance over extended use.
- High Strength & Toughness: Combines high mechanical strength with excellent toughness and impact resistance, making it suitable for components exposed to mechanical stress and repeated loads.
- Excellent Thermal Performance: Maintains reliable mechanical properties and flexibility across a broad temperature range, supporting demanding applications involving both elevated and low temperatures.
- Strong Chemical & Oil Resistance: Provides good resistance to oils, fuels, greases, and a wide range of chemicals, helping maintain material performance in challenging service environments.
- Reliable Processability: Offers stable melt processing and can be efficiently manufactured using common thermoplastic methods, including injection molding, extrusion, blow molding, and other forming processes.
