Ertalyte® PET-P Plastic Products

ErtalyteShop for Ertalyte online at Modern PlasticsErtalyte® PET-P, manufactured by Quadrant Engineering Plastic Products, is an excellent choice for close tolerance parts. Available in sheet, rod, tube, and plate forms, Ertalyte is manufactured from proprietary resin grades; it is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). Ertalyte® PET-P is characterized as having the best dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. Ertalyte® properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions. Its continuous service temperature is 210°F (100°C) and its melting point is almost 105°F higher than acetals.

In addition, Ertalyte® PET-P offers good chemical and abrasion resistance. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture. Modern Plastics stocks Ertalyte in sheet, rod, tube, and plate forms and also stocks Ertalyte TX, an internally lubricated grade of Ertalyte with enhanced properties.

Ertalyte® is FDA compliant in natural or black colors. Natural (white) Ertalyte is also USDA, 3A-Dairy compliant and Canada AG compliant. Ertalyte® is an excellent candidate for parts used in the food processing and equipment industries.

Only Quadrant Engineering Plastic Products offers brand-name Ertalyte® stock shapes.

Engineering Notes:

Ertalyte® and other polyesters have less resistance to hot water than Acetron® GP acetal. Also, since Ertalyte® is more rigid and offers greater thermal performance than nylon and acetal, Ertalyte® machines differently. For best results, please contact us at Modern Plastics to request a copy of "Ertalyte® PET-P Design and Fabrication Guide."

Ertalyte® TX is an internally lubricated thermoplastic polyester providing enhanced wear and inertness over general purpose nylon(PA) and acetal(POM) products. Containing uniformly dispersed solid lubricant, Ertalyte® TX provides a lower wear rate and coefficient of friction than unmodified polyesters like PET or PBT, and even internally lubricated materials like Delrin® AF blend.
