Material Notes:

Pomalux is a high performance acetal copolymer that has excellent mechanical, electrical, and wear properties. It is engineered to provide outstanding dimensional stability, even when machining parts with complex geometries. It is a good choice for many bearing and wear applications since it has a low coefficient of friction and wears well in both wet and dry environments. Information provided by Westlake Plastics.
