Ertalyte® TX PET
Polyethylene Terephthalate
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.

Material Properties

• High mechanical strength, stiffness, and hardness
• Very good creep resistance
• Low and constant coefficient of friction
• Excellent wear resistance (comparable to or even better than Nylon grades)
• Very good dimensional stability (better than Polyacetal)
• Physiologically inert (suitable for food contact)
