PET-P (Polyethylene Terephthalate) - Ertalyte®, Sustadur®

PET-P is characterized as having the best dimensional stability coupled with excellent wet resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions.  These properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions.  It has a continuous service temperature of 210°F (100°C) and its melting point is almost 150°F higher than acetals.  PET-P retains significantly more of its original strength up to 180°F (85°C) than nylon or acetal.  It also offers good chemical and abrasion resistance and its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture.
