POM

polymer

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.

Regulatory Screening

Environmental

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
