Thermoplastic Copolyester Elastomer (TPC-ET), also known as COPE, is a high-performance thermoplastic elastomer that combines the resilience of rubber with the strength and chemical resistance of polyester. TPC-ET is used in applications requiring flexibility, durability, and resistance to fatigue and chemicals.Thermoplastic Copolyester Elastomer (TPC-ET), also known as COPE, is a high-performance thermoplastic elastomer that combines the resilience of rubber with the strength and chemical resistance of polyester.

• Automotive: CV joint boots, cable insulation, flexible connectors, fuel line components.
• Industrial: Gears, belts, seals, vibration dampers, and bushings.
• Consumer goods: Footwear inserts, sporting goods, and soft grip handles.
• Electrical: Cable jackets and insulation requiring flexibility and chemical resistance.
• Elasticity and resilience: Offers rubber
• like flexibility with long
• term recovery and fatigue resistance.
• Thermal resistance: Operates in temperatures from –40 °C to +135 °C, depending on grade.
• Excellent chemical resistance: Withstands oils, greases, fuels, and many cleaning agents.
• Processability: Easily processed by injection molding, extrusion, or blow molding.
• Abrasion resistance: Maintains integrity under repeated mechanical stress and friction.
• Higher cost: More expensive than standard thermoplastics like PP or PE.
• Limited UV resistance: Requires stabilizers for outdoor applications.
• Less soft feel: Compared to other TPEs, it has higher hardness.
