PET(polyethylene terephalate)

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.  Because PET has no centerline porosity, the possibilty of fluid absorption and leakage is virtually eliminated.
