Sustadur PET


Sustadur PET Product Description


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



Key Features and Benefits:
  • 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
