Material Notes:
Ertalyte TX is a polyethylene terephthalate compound incorporating a uniformly dispersed solid lubricant. Its specific formulation makes it a premium internally lubricated bearing-grade. Ertalyte TX not only has got an outstanding wear resistance, but offers in comparison with Ertalyte an even lower coefficient of friction as well as higher pressure-velocity capabilities. High mechanical strength, stiffness and hardness Very good creep resistance Low and constant coefficient of friction Excellent wear resistance (comparable to or even better than Nylon grades) Very good dimensional stability (better than Polyacetal) Excellent stain resistance Better resistance to acids than Nylon or Polyacetal Good electrical insulating properties Physiologically inert (suitable for food contact) Good resistance to high energy radiation (gamma- and X-rays)
