Ertalyte TX Polyethylene Terephthalate Polyester PET FG (Food Grade) is an unreinforced, semi-crystalline grade that exhibits superior dimensional stability, excellent 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 FG 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. Due to these characteristics, and this grade’s FDA (compositional FDA 21 CFR § 177.2470) and EU 10/2011 food compliant composition, Ertalyte TX PET FG components are a favored solution 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.
