POM (polyoxymethylene), also known as acetal, is a crystalline engineering thermoplastic characterized by high stiffness, low friction, and excellent dimensional stability. It is widely used in precision-molded components where tight tolerances, wear resistance, and chemical inertness are critical, making it a go-to choice over softer plastics like polyethylene or polypropylene in demanding mechanical applications.
