ABS vs PPSU (Polyphenylsulfone)
Side-by-side chemical composition and mechanical property comparison.
Overview
ABS
Acrylonitrile Butadiene Styrene — the most widely used amorphous engineering/commodity thermoplastic. Excellent balance of toughness, rigidity, and processability. Good surface finish and paintability. Not UV-stable without additives. Trade names include Novodur (INEOS Styrolution), Terluran (INEOS), Cycolac (SABIC). Used for automotive interior trim, appliance housings (vacuum cleaners, monitors), LEGO bricks, 3D printing filament, and pipe fittings.
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.
