Ertalyte® is an unreinforced, semi-crystalline, thermoplastic polyester based on polyethylene teraphalate (PET-P). It has a continuous service temperature of 210°F (100°C) and its melting point is almost 150°F higher than acetals. It offers dimensional stability with excellent wear resistance, low coefficient of friction, high strength, and resistance to moderate acid solutions. The properties of Ertalyte® make it extremely suitable for the manufacture of precision mechanical parts, which are capable of sustaining high loads and enduring wear conditions. Ertalyte® is FDA compliant in both natural and black colors. Natural Ertalyte is also USDA, 3A-Dairy and Canada AG compliant. It is an excellent candidate for parts used in the food processing and equipment industries. Ertalyte® TX is an internally lubricated version of PET-P, providing enhanced wear and inertness over general purpose Nylons® or acetals. Containing uniformly dispersed solid lubricant, Ertalyte® TX provides a lower wear rate and coefficient of friction than unmodified PET or PBT and even internally lubricated materials such as Delrin® AF. Ertalyte® TX is light gray in color.
