ABS vs PVC-U (Rigid PVC)
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.
PVC-U (Rigid PVC)
Unplasticized Polyvinyl Chloride — the second-most produced plastic globally. Hard, rigid, self-extinguishing (LOI 45%), excellent chemical resistance to acids/bases/salts, and very low cost. Key limitation: max service temp only 60°C. Developed in 1930s Germany. Used for water/sewage pipes, window profiles, electrical conduit, cladding, and chemical tanks/fittings. NOT the flexible PVC used in cables — that is PVC-P (plasticized).
