Ertalyte™ is a family of unreinforced, semi-crystalline thermoplastic  polyester based on polyethylene terephthalate (PET) products. The  specific properties of virgin crystalline PET make it especially suitable for the manufacture of mechanical precision parts must endure high loads and wear conditions. It is characterized as having excellent  dimensional stability coupled with excellent wear resistance, a low  coefficient of friction, high strength, and resistance to moderately  acidic solutions. Ertalyte™'s continuous service temperature is 210°F (100°C) and its melting point is almost 150°F higher than acetals. It retains significantly more of its original strength up to 180°F (85°C) than nylon or acetal. For food-grade PET, Ertalyte™ grades are excellent candidates for parts used in the food processing and equipment industries.
