ASA (Acrylonitrile-Styrene-Acrylate) vs PE-LD (Low-Density Polyethylene)
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.
PE-LD (Low-Density Polyethylene)
Low-density polyethylene — branched chain structure gives flexibility, transparency, and easy processing. THE film/packaging polymer: cling wrap, carrier bags, squeeze bottles, shrink wrap. Also used for cable insulation, agricultural film, and coatings. Lower density (0.91-0.93) and strength than PE-HD but much more flexible.
