Sustadur® PET thermoplastic polyester products are semi-crystalline materials that offer good wear resistance along with a combination of excellent thermal stability and chemical resistance.

Sustadur® PET (polyethylene terephthalate) offers higher strength and stiffness over acetal, nylon and PBT. This product has outstanding dimensional stability by virtue of low moisture absorption and a low coefficient of thermal expansion.
