Brief Introduction of POM Materials

POM (Polyoxymethylene) is an engineering thermoplastic material that demonstrates excellent dimensional stability, stiffness and impact and temperature resistance. The material, also known as acetal or Delrin, can be produced two ways: as a homopolymer or as a copolymer.

POM materials are commonly used in the fabrication of pipe components, gear bearings, household appliances, automotive parts, consumer electronics and more.

General Information for POM

POM is supplied in a granulated form and can be formed into the desired shape by applying heat and pressure. The two most common forming methods employed are injection molding and extrusion. Rotational molding and blow molding are also possible.

Typical applications for injection-molded POM include high-performance engineering components (e.g. gear wheels, ski bindings, yoyos, fasteners, lock systems). The material is widely used in the automotive and consumer electronics industry. There are special grades that offer higher mechanical toughness, stiffness or low-friction/wear properties.
POM is commonly extruded as continuous lengths of round or rectangular section. These sections can be cut to length and sold as bar or sheet stock for machining.
