ABS vs ASA (Acrylonitrile-Styrene-Acrylate)
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.
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.
