Ertalyte™ PET-P is an unreinforced, semi-crystalline grade produced from our proprietary resins and characterized by its excellent wear resistance, low coefficient of friction, high strength and resistance to moderately acidic solutions. This grade is capable of sustaining high loads and retains more of its original strength up to 85°C (180°F) than nylons or acetals. Due to these characteristics, Ertalyte™ PET-P components are a favored solution for bearing and structural applications throughout the pharmaceutical, food processing & packaging and oil & gas industries.
