PET is an unreinforced, semi-crystalline thermo-plastic polyester derived from polyethylene terephthalate. Its excellent wear resistance, low coefficient of friction, high flexural modulus, and superior dimensional stabilty make it a versatile material for designing mechanical and electro-mechanical parts.ET is an unreinforced, semi-crystalline thermo-plastic polyester derived from polyethylene terephthalate.
