Polyoxymethylen – POM


In General | Technical Data of POM | Advantages | Tradenames of POM

POM, short for polyoxymethylene, is one of the semi-crystalline thermoplastics. This plastic is often used as a construction material because it has better mechanical properties than other standard plastics. In general, plastic profiles made from this material have advantageous properties such as high strength, hardness, stiffness, wear resistance and low coefficients of friction. Impact strength is maintained even at temperatures as low as about -40°C. Further, POM is a very durable plastic and absorbs moisture only to a small extent.

This plastic also distinguishes between two types. POM-H has a higher density, hardness and strength. POM-C, on the other hand, has higher impact strength, abrasion resistance and chemical resistance.

POM is used for thin-walled precision parts such as slide guides, coupling components, bearings, sliding elements and much more, for example for the automotive industry, electrical engineering or mechanical engineering.

Binder + Wöhrle processes POM in the field of plastic extrusion as well as in plastic injection molding. B + W has different types in use and produces customized plastic tubes, hoses -profiles, -sheathings, ¬connection parts and much more in the diameter range of 0.5 – 50 mm.
