ASA (Acrylonitrile-Styrene-Acrylate) vs PP (Polypropylene)
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 (Polypropylene)
Polypropylene is the most produced plastic globally by volume. Semi-crystalline thermoplastic with excellent chemical resistance, low density (0.90–0.91 g/cm³ — lightest engineering plastic, floats in water), good fatigue resistance (living hinges) and low cost. Available as homopolymer (higher stiffness) and copolymer (better impact). Trade names: Moplen (LyondellBasell), Sabic PP (SABIC), Borealis PP. Used for packaging, automotive bumpers/interiors, medical devices, piping, hinges, containers, textiles (nonwoven) and household goods.
