ABS vs PPS (unfilled)
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.
PPS (unfilled)
Polyphenylene Sulfide — semi-crystalline high-performance thermoplastic. Broadest chemical resistance of any engineering plastic — no known solvents below 200°C. Inherently flame-resistant (V-0 without additives, LOI 44%). Very low moisture absorption (<0.02%). Brittle in unfilled form — usually glass-fiber reinforced for structural use. Trade names include Ryton (Solvay), Fortron (Celanese), Torelina (Toray), Durafide (Polyplastics). Used for chemical pump components, filter bags, electrical insulation, and as base resin for GF40 compounds.
