ABS vs PVDF (Kynar)
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.
PVDF (Kynar)
Polyvinylidene Fluoride — the melt-processable fluoropolymer. Bridges the gap between PTFE (non-melt-processable) and conventional plastics. Excellent chemical resistance to acids, solvents, and hydrocarbons. Uniquely piezoelectric among polymers. Much stronger than PTFE (UTS 50 vs 25 MPa). Trade names include Kynar (Arkema), Solef/Hylar (Solvay), KF (Kureha). Used for chemical piping/valves/tanks, lithium-ion battery binder, semiconductor wet bench, architectural coatings (Kynar 500), and piezoelectric sensors.
