PC/ABS (Blend) vs ABS: PC/ABS adds heat and impact resistance over pure ABS
PC/ABS (Blend) vs ABS
Side-by-side chemical composition and mechanical property comparison.
Overview
PC/ABS (Blend)
Polycarbonate + ABS blend — one of the most widely used industrial thermoplastic alloys. Combines PC impact strength and heat resistance with ABS processability and lower cost. Better chemical resistance than pure PC. Properties tunable by PC/ABS ratio. Trade names include Bayblend (Covestro), Cycoloy (SABIC), Pulse (Techpolymers). Used for automotive dashboards, laptop/phone housings, power tool casings, and 3D printing (FDM filament).
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.
