产品说明

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. Pomalux is an excellent choice for many bearing and 
wear applications since it has low coefficient of friction and wears well in both wet and dry environments. It is widely used for assembly jigs and 
fixtures because of its inherent dimensional stability and excellent wear properties. Pomalux is often specified for electrical applications when low 
moisture absorption and high dielectric strength are required. Both natural (white) and black Pomalux are FDA compliant for use in food 
processing machinery.
