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.
