Thermoplastic copolyester (TPC), also known as TPE-E or COPE (copolyester elastomer), is a flexible engineering thermoplastic combining the elasticity of rubber with the strength and chemical resistance of polyester. As one of the most widely used thermoplastic elastomers, it offers a long service life, thermal resistance, and ease of processing.Thermoplastic copolyester (TPC), also known as TPE-E or COPE (copolyester elastomer), is a flexible engineering thermoplastic combining the elasticity of rubber with the strength and chemical resistance of polyester.

• Automotive: Seals, cable boots, bellows, fuel tubes, couplings, flexible joints.
• Electronics: Cable protection, connectors, tension elements, insulation components.
• Industrial equipment: Flexible gears, belts, shock absorbers, and soft mountings.
• Sportswear and accessories: Shoe inserts, gear parts, straps, and flexible bags.
• Household goods: Handles, soft grips, closures, seals, and flexible tool components.
• Elasticity and flexibility: Behaves like rubber with lasting deformation recovery under repeated stress.
• Thermal resistance: Operates from –40 °C to +135 °C depending on grade.
• Excellent chemical resistance: Resists fuels, oils, greases, cleaners, and solvents.
• Fatigue resistance: Withstands dynamic loads and retains properties over many bending cycles.
• Easy processing: Can be injection molded, extruded, or blow molded without vulcanization.
• Higher cost than basic thermoplastics: More expensive than PP or PE due to its composition.
• Limited UV resistance without additives: Requires UV stabilization for outdoor use.
• Higher hardness than some TPEs (e.g., TPE
• S): Less suitable for very soft
• touch applications.
