Ertalyte® High Performance PET-P Products

Ertalyte® is a family of unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P) products. The specific properties of virgin crystalline PET make it especially suitable for the manufacture of mechanical precision parts must endure high loads and wear conditions. It is characterized as having excellent dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. Ertalyte®'s continuous service temperature is 210°F (100°C) and its melting point is almost 150°F higher than acetals. It retains significantly more of its original strength up to 180°F (85°C) than nylon or acetal. For food-grade PET-P, Ertalyte® grades are excellent candidates for parts used in the food processing and equipment industries.

Products in the Ertalyte® family (6)

Ertalyte® TX Food Grade PET-P

Ertalyte® TX Food Grade PET-P 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 its low moisture absorption rate, this grade’s mechanical and electrical properties are unaffected by moisture, which gives this grade better wear and inertness than nylon and acetal products, as well as 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 Food Grade PET-P 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.
