ABS vs PEEK (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.
PEEK (unfilled)
Polyetheretherketone — the premium engineering thermoplastic. Exceptional mechanical properties maintained to 260°C continuous use. Resistant to virtually all organic solvents and acids. Biocompatible (ASTM F2026). Used as metal replacement in aerospace, automotive engine parts, medical implants (spinal cages), semiconductor wafer handling, and oil/gas downhole seals.
