SUSTADUR® 

PETP (Thermoplastic Polyester)

Sustadur® PETP (Polyethylene Terephthalate) is a highly crystalline thermoplastic polyester.

It has high mechanical strength, good resistance to creep, excellent dimensional stability, abrasion resistance and excellent gliding properties especially very smooth surfaces such as aluminium.

Although it absorbs very little moisture Sustadur® PETP does suffer from hydrolysis and should not be used in aqueous applications at temperatures above 70ºC or steam environments.

It offers superior wear resistance to Sustarin® C Acetal and is an excellent material for close tolerance parts.

Important Note: Due to Sustadur® PETP’s high crystalline structure it is notch sensitive so therefore care needs to be taken when used in possible impact or shock loading applications.

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