General Info

Pomalux Polyoxymethylene (POMC) is a high-performance acetal copolymer used for a wide range of applications. Pomalux has good chemical and high-temperature resistance.

As a semi-crystalline material, Pomalux has good wear resistance and low frictional characteristics.

Pomalux also has low moisture absorption making Pomalux a good candidate for a wide range of structural and mechanical components that carry or transmit loads in dry or wet environments.

Both natural and black Pomalux natural are FDA compliant.

Pomalux ®

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.

Available Sizes
