Pomalux is a high-performance acetal copolymer that has excellent mechanical, electrical,

and wear properties. It is engineered to provide outstanding dimensional stability, even wh

en machining parts with complex geometries. Pomalux is an excellent choice for many bea

ring and wear applications since it has low coefficient of friction and wears well in both we

t and dry environments. It is widely used for assembly jigs and fixtures because of its inhere

nt dimensional stability and excellent wear properties. Pomalux is often specified for electric

al applications when low moisture absorption and high dielectric strength are required. Bot

h natural (white) and

black Pomalux are FDA compliant for use in food processing machinery. Westlake Plastics C

ompany manufactures all Acetal extruded & compression molded sheets, plates and rods in

accordance to ASTM D6100. This specification covers requirement and test methods for the m

aterial, dimensions, workmanship and the properties of extruded and compression molded sh

eets, plates and rods.
