PA12 (Nylon 12) vs POM-H (Acetal Homopolymer)
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-H (Acetal Homopolymer)
Polyoxymethylene Homopolymer — slightly stronger and stiffer than POM-C copolymer but with centerline porosity in stock shapes and lower resistance to hot water/alkalis. Trade names include Delrin (DuPont/DuPont de Nemours) and Tenac (Asahi Kasei). Used for gears, cams, springs, clips, fuel system components, and precision-machined parts where maximum stiffness is needed.
