ASA (Acrylonitrile-Styrene-Acrylate) vs PPSU (Polyphenylsulfone)
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.
PPSU (Polyphenylsulfone)
Polyphenylsulfone — highest-performance sulfone polymer. Better impact and chemical resistance than PSU and PEI. Withstands >1000 steam autoclave cycles at 134°C without property loss. Tg 220°C. Transparent amber, colorable. Inherently flame-retardant (V-0). FDA/USP Class VI/ISO 10993 compliant. Trade name: Radel (Solvay/Syensqo), Ultrason P (BASF). Used for reusable medical instrument trays, surgical instrument handles, dental tools, aircraft interior panels, and hot-water plumbing fittings.
