ASA (Acrylonitrile-Styrene-Acrylate) vs EPDM (Ethylene Propylene Diene Rubber)
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.
EPDM (Ethylene Propylene Diene Rubber)
Ethylene propylene diene monomer rubber — THE outdoor/weather elastomer. Saturated backbone gives outstanding ozone, UV, and weathering resistance. Excellent resistance to steam, hot water, and polar solvents. NOT resistant to oils/fuels (opposite of NBR). Good electrical insulation. ρ 0.85-1.3 (lightest common rubber). Used for automotive door/window seals, roofing membranes, radiator hoses, HVAC gaskets, and pond liners.
