ASA (Acrylonitrile-Styrene-Acrylate) vs PP-H (Polypropylene Homopolymer)
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.
PP-H (Polypropylene Homopolymer)
Polypropylene Homopolymer — the lightest common engineering plastic (0.905 g/cm³). Excellent chemical resistance (esp. to acids and bases), good fatigue resistance (integral living hinges), and low moisture absorption. Becomes brittle below 0°C. Used for chemical tanks, HVAC ducts, pump housings, food containers, automotive battery cases, and medical lab equipment.
