SUSTADUR« Polyethylene Terephthalate (PETP) 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« does suffer from hydrolysis and should not be used in aqueous applications at temperatures above 70║C or steam environments.

It also has superior wear resistance compared to SUSTARIN« C Acetal copolymer and is an excellent candidate for close tolerance parts however due to its high crystalline structure it is notch sensitive so therefore care needs to be taken when used in possible impact or shock loading applications.
