PET-ERTALYTE
Polyethylene Terephthalate (PET) is an unreinforced, semi-crystalline 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 PET has no centerline porosity, the possibility of fluid absorption and leakage is virtually eliminated. PET can also be used in water purification systems, printing equipment, textile components, food-handling equipment, and valves.
