Ertalyte® PET-P -manufactured by Quadrant Engineering Plastic Products from proprietary resin grades, is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). Ertalyte® is characterized as having the best dimensional stability couple with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. Ertalyte® properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions. It's continuous service temperature is 210°F (100°C) and its melting point is almost 105°F higher than acetals.

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® is FDA compliant in natural or black colors. Natural (white) Ertalyte is also USDA, 3A-Dairy compliant and Canada AG compliant. Ertalyte® is an excellent candidate for parts used in the food processing and equipment industries.

Only Quadrant Engineering Plastic Products offers brand-name Ertalyte® stock shapes.

Engineering Notes:

Ertalyte® and other polyesters have less resistance to hot water than Acetron® GP acetal. Also, since Ertalyte® is more rigid and offers greater thermal performance than nylon and acetal, Ertalyte® machines differently. For best results, please contact David A.
