PA12 (Nylon 12) vs PA66 GF30
Side-by-side chemical composition and mechanical property comparison.
Overview
PA12 (Nylon 12)
Polyamide 12 — the long-chain polyamide with the lowest moisture absorption of all PA grades (0.1-0.15% vs PA6: 1.5%). Excellent dimensional stability in humid environments. Best chemical resistance among polyamides (oils, fuels, hydraulic fluids). Lowest density of all PA (1.01 g/cm³). Also the dominant 3D printing (SLS/MJF) material. Trade names include Rilsamid (Arkema), Grilamid L (EMS), TECAMID 12 (Ensinger), Vestamid L (Evonik). Used for fuel lines, brake lines, pneumatic tubing, cable sheathing, and 3D-printed functional parts.
PA66 GF30
Polyamide 66 with 30% short glass fiber — stronger and more heat-resistant than PA6 GF30 due to higher-Tm base polymer. UTS ~190 MPa dry, HDT ~250°C. THE automotive under-hood material for structural brackets. Trade names include Ultramid A3WG6 (BASF), Zytel 70G30 (DuPont), Durethan AKV 30 (LANXESS), Technyl A218 V30 (Domo). Used for engine brackets, radiator end tanks, air intake manifolds, and electrical connectors.
