ABS vs POM-C (Acetal Copolymer): 0% composition overlap. Significantly different materials serving different application areas.
ABS vs POM-C (Acetal Copolymer)
Side-by-side chemical composition and mechanical property comparison.
Overview
ABS
Acrylonitrile Butadiene Styrene — the most widely used amorphous engineering/commodity thermoplastic. Excellent balance of toughness, rigidity, and processability. Good surface finish and paintability. Not UV-stable without additives. Trade names include Novodur (INEOS Styrolution), Terluran (INEOS), Cycolac (SABIC). Used for automotive interior trim, appliance housings (vacuum cleaners, monitors), LEGO bricks, 3D printing filament, and pipe fittings.
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.
