Ertalyte and PET Rod, Sheet and Tube


Ertalyte Product Description


The specific properties of this virgin crystalline Ertalyte PET rod & sheet make it specially suited for the manufacture of mechanical precision parts which have to sustain high loads and/or are subject to wear.



Key Benefits of Ertalyte:
  • High mechanical strength, stiffness and hardness
  • Very good creep resistance
  • Excellent wear resistance (comparable or even better than Nylon grades)
  • Very good dimensional stability (better than polyacetal)
  • Excellent stain resistance
  • Better resistance to acids than nylon and polyacetal.
  • Good electrical insulating properties
  • Physiologically inert (suitable for food contact)
  • Good resistance to high energy radiation (Gamma and X-rays)

 

Polyester Plastics Applications:

  • Precision gears and bearings
  • Thrust washers
  • Pump components
  • Slideways
  • Components for mechanisms of precisions
