ASA (Acrylonitrile-Styrene-Acrylate) vs PEEK (unfilled)
Side-by-side chemical composition and mechanical property comparison.
Overview
ASA (Acrylonitrile-Styrene-Acrylate)
UV-resistant alternative to ABS — acrylic rubber replaces butadiene for excellent weatherability. Retains color and gloss outdoors for years without coating. Similar mechanical properties to ABS but with 10× better UV resistance. Trade names: Luran S (BASF/INEOS), Geloy (SABIC). Used for automotive exterior trim, outdoor electrical housings, garden furniture, and building cladding.
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.
