Material Notes:

ENSITEP 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 ENSITEP has no centerline porosity, the possibility of fluid absorption and leakage is virtually eliminated. Uses: ENSITEP's superior wear resistance and lack of centerline porosity give it an advantage over other materials for applications involving solvents, chemicals, and food products. ENSITEP is also used in water purification systems, printing equipment, textile components, food-handling equipment, and valves.Information supplied by Ensinger, Inc.Ensitep grades have been replaced by Tecapet
