Rigidity Acetal Pom Sheet   Polyoxymethylene (POM), also known as acetal, polyacetal and polyformaldehyde is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability. As many other synthetic polymers, it is produced by different chemical firms with slightly different formulas and is therefore sold under many commercial names like Delrin, Celcon, Hostaform, etc. It was discovered by Hermann Staudinger, a German chemist who received the 1953 Nobel Prize in Chemistry. He studied the polymerization and structure of POM in the 1920s to research the theory of macromolecules, which he characterized as polymers. Due to initial problems with thermal stability, POM was not commercialized.    Rigidity Acetal POM SHEET
