Sustadur® PET

SUSTADUR® (Polyethylene Terephthalate) has high mechanical strength, good resistance to creep, excellent dimensional stability and excellent sliding properties. SUSTADUR® has superior wear resistance compared to acetal and is ideal for close tolerance parts such as gears and plastic bushes and split bushes.

Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture making this material ideally suited as a bronze bush replacement. SUSTADUR® can be machined to precise detail on standard metal working equipment.
