WebPolyoxymethylene (POM), also known as acetal, polyacetal and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. WebThis leads to cracks in parts during long-term use. The shrinkage of molded plastic parts can be as much as 20% by volume when measured at the processing and ambient temperature. This volume contraction of polymers often leads to wrapped parts and dimension differences. These changes occur between manufactured parts and the mold.
