Ertalyte® Machinable Polyester Plastic
Ertalyte® is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). It is manufactured from proprietary resin grades made by MCAM. Ertalyte® is characterized as having the best dimensional stability coupled with excellent wear resistance, 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. Ertalyte® retains significantly more of its original strength up to 180°F (85°C) than nylon or acetal.
