ABS vs PPA (Polyphthalamide)
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.
PPA (Polyphthalamide)
Polyphthalamide — semi-aromatic high-performance polyamide. 55%+ aromatic diacid (TPA/IPA) gives Tg ~125°C and Tm >310°C — far above PA66 (Tg 50°C, Tm 260°C). Much lower moisture absorption than aliphatic PAs. SMT-reflow compatible (260°C+). Trade names: Amodel (Solvay/Syensqo), Zytel HTN (Celanese), Ultramid T (BASF), Grivory HT (EMS). Used for automotive powertrain (thermostat housings, charge air coolers), SMT connectors, LED headlamp housings, and metal-replacement applications to 280°C.
