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 servicemore
