PET is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET). 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. PET's properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions. PET's continuous service temperature is 210° F and its melting point is almost 150° F higher than Acetal. It retains significantly more of its original strength up to 180° F than Nylon or Acetal. In addition, PET offers good chemical and abrasion resistance. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture. PET can be machined to precise detail on standard metal working equipment.
