Ertalyte® is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). Ertalyte® is manufactured from proprietary resin grades. Only Quadrant can offer Ertalyte®. Ertalyte® 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. 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.
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. 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.
Because it is more rigid and offers greater thermal performance than nylon and acetal, Ertalyte® machines differently. For best results, please request a copy of Quadrant's design and fabrication guideline for Ertalyte® PET-P. Ertalyte® and other polyesters have less resistance to hot water than Acetron® GP acetal.
