Polyester PET (Ertalyte)

Polyester PET (Ertalyte) is a virgin crystalline PET. The specific properties of this product make it specially suited for the manufacture of mechanical precision parts which have to sustain high loads and/or are subject to wear.

Features and Benefits of Polyester PET (Ertalyte):

Polyester PET (Ertalyte) has similar properties to Acetal, with:

  • Improved tensile strength
  • Dimensional stability
  • Operating temperature
  • Reduced notched impact resistance
  • High mechanical strength, stiffness & hardness
  • Very good creep resistance
  • Excellent wear resistance (comparable or even better than Nylon grades)
  • Very good dimensional stability (better than acetal)
  • Excellent stain resistance
  • Better resistance to acids than nylon and acetal.
  • Good electrical insulating properties
  • Physiologically inert (suitable for food contact)
  • Good resistance to high energy radiation (Gamma and X-rays)

Applications of Polyester:

  • Precision gears and bearings
  • Thrust washers
  • Pump components
  • Slideways
  • Components for mechanisms of precision, etc
