Ensinger TECAPET®

About
TECAPET®PET is an unreinforced, semicrystalline thermoplastic polyester derived from polyethylene terephthalate. Its excellent wear resistance, low coefficient of friction, high flexural modulus, and superior dimensional stability make it a versatile material for designing mechanical and electro-mechanical parts. Because TECAPET®PET has no centerline porosity, the possibility of fluid absorption and leakage is virtually eliminated. TECAPET™PET superior wear resistance and lack of centerline porosity give it an advantage over other materials for applications involving solvents, chemicals, and food products. TECAPET™PET is also used in water purification systems, printing equipment, textile components, food-handling equipment, and valves. Excellent wear resistance Low coefficient of friction Very good chemical resistance No centerline porosity eliminates the possibility of fluid absorption and leakage Good electrical insulator High mechanical strength Excellent hardness and stiffness Good weather resistance Low water absorption Good resistance to high-energy radiation&&
