POM (Poly-oxy-methylene)

SmithPlast POM is a white (natural) Polyacetal, commonly referred to as POM (Polyoxymethylene) or Acetal. This material has excellent physical and chemical properties to serve a wide range of applications. POM is very stable in wet and dry environments and is recommended for precision and close tolerance parts. POM has very low moisture absorption compared to standard nylons and is also FDA approved.

Application :-

It is mainly used in friction bearings, friction strips, gears, plugs, tool supports, insulators, housing parts, guide rings, bushes and as high precision parts.
