Polyethylene terephthalate (PET), more commonly known as Polyester, is a durable, tough thermoplastic with good chemical, high energy radiation, weather, wear and abrasion resistance.
PET-P material under the tradename of Ertalyte® is produced by proprietary resin grades made by Quadrant. Ertalyte® PET-P is an unreinforced, semi-crystalline thermoplastic polyester characterized as having the best dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, low water absorption, and resistance to moderately acidic solutions. Its properties make it a good choice for tight tolerance machining, especially the manufacture of precision mechanical parts which require sustaining high loads and enduring wear conditions.
Also Consider Ertalyte TX , an internally lubricated version of PET-P, which provides enhanced wear and inertness over general purpose nylons or acetals.
