Ertalyte® TX - Wear resistant PET

Ertalyte® TX Polyethylene Terephthalate Polyester PET is a premium internally lubricated bearing-grade that exhibits superior dimensional stability and wear resistance, a low coefficient of friction, high strength and rigidity, outstanding stain resistance, and great chemical and abrasion resistance. Due to Ertalyte® TX PET’s low moisture absorption rate, this grade’s mechanical and electrical properties are unaffected by moisture, which gives this grade better wear and inertness over nylon and acetal products, and also a lower wear rate than unmodified polyesters. These characteristics make Ertalyte® TX PET ideal for use in applications that involve high pressure and velocity conditions, and environments with soft metal and plastic mating surfaces where noise abatement is critical.
