Polyoxymethylene (POM), also known as acetal, is a semi-crystalline polymer material and belongs to engineering thermoplastics. It offers high stiffness, low friction, low wear and excellent chemical resistance and is often used as a substitute for metals. In principle, POM resins can be processed by all methods suitable for thermoplastics. However, the most important methods are injection molding and extrusion. Since its commercialization in the 1960s, POM has developed into a plastic material specifically for technical applications. POM can be found in everything from large functional parts in the automotive and mechanical engineering industries to tiny precision parts in drug delivery systems.
