Ertalyte is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). It is manufactured from proprietary resin grades made by Quadrant. Only Quadrant can offer Ertalyte. It is characterized as having the best dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. Ertalyte's properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions. Ertalytes 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 (See Figure 9).
In addition, Ertalyte PET-P offers good chemical and abrasion resistance. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture (See Figure 11). Ertalyte PET-P can be machined to precise detail on standard metal working equipment.
Ertalyte is FDA compliant in natural and black. Natural Ertalyte is also USDA, 3A-Dairy and Canada AG compliant. Ertalyte is an excellent candidate for parts used in the food processing and equipment industries.
