PA12 (Nylon 12) vs POM-C (Acetal Copolymer)
Side-by-side chemical composition and mechanical property comparison.
Overview
PA12 (Nylon 12)
Polyamide 12 — the long-chain polyamide with the lowest moisture absorption of all PA grades (0.1-0.15% vs PA6: 1.5%). Excellent dimensional stability in humid environments. Best chemical resistance among polyamides (oils, fuels, hydraulic fluids). Lowest density of all PA (1.01 g/cm³). Also the dominant 3D printing (SLS/MJF) material. Trade names include Rilsamid (Arkema), Grilamid L (EMS), TECAMID 12 (Ensinger), Vestamid L (Evonik). Used for fuel lines, brake lines, pneumatic tubing, cable sheathing, and 3D-printed functional parts.
POM-C (Acetal Copolymer)
Polyoxymethylene Copolymer — the precision engineering plastic. Exceptional dimensional stability, low moisture absorption (0.2%), low friction coefficient, and excellent machinability. More hydrolysis-resistant and chemically stable than POM-H (homopolymer). No centerline porosity in stock shapes. Trade names include Hostaform (Celanese), Ertacetal C (MCAM), Duracon (Polyplastics). Used for gears, bearings, valve bodies, pump parts, electrical insulators, and food/medical contact parts.
