Material Notes:
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 eliminatedExcellent wear resistanceLow coefficient of frictionVery good chemical resistanceNo centerline porosity eliminates the possibility of fluid absorption and leakageGood electrical insulatorHigh mechanical strengthExcellent hardness and stiffnessGood weather resistanceIn compliance with FDA regulations 21 CFR 177.1630 for use in contact with foodLow water absorptionGood resistance to high-energy radiationTECAPET™ 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.Information Provided by Ensinger Industries, Inc.
