ASA (Acrylonitrile-Styrene-Acrylate) vs POM-C (Acetal Copolymer)
Side-by-side chemical composition and mechanical property comparison.
Overview
ASA (Acrylonitrile-Styrene-Acrylate)
UV-resistant alternative to ABS — acrylic rubber replaces butadiene for excellent weatherability. Retains color and gloss outdoors for years without coating. Similar mechanical properties to ABS but with 10× better UV resistance. Trade names: Luran S (BASF/INEOS), Geloy (SABIC). Used for automotive exterior trim, outdoor electrical housings, garden furniture, and building cladding.
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.
