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.

Ertalyte® TX excels under both high pressure and velocity conditions. It is also ideally suited for applications involving soft metal and plastic mating surfaces.  Ertalyte® TX is also FDA, USDA and 3A-Dairy compliant.

Key Benefits:

•Outstanding wear resistance
•Excellent dimensional stability
•FDA compliance

•Low and constant coefficient of friction (low slip stick)
•Low water absorption
•Easy to machine 


•Linear bearings
•Wear and slide pads
•Dynamic seals
•Scraper blades
•Thrust washers
•Valve seats
•Rollers and wheels without bearings
•Journal bearings

Ertalyte® TX - FDA Compliant, PET outwears other nylon, Acetal and Polyester Materials.
