PA12 (Nylon 12) vs PP 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.
PP GF30
Polypropylene with 30% short glass fiber — a cost-effective alternative to PA GF30 for applications up to ~130°C. Much cheaper base resin (PP vs PA), zero moisture sensitivity, and excellent chemical resistance. Lower strength than PA6 GF30 (UTS 80 vs 175 MPa) but sufficient for many structural parts. Trade names include Celstran PP-GF30 (Celanese), Tepex (LANXESS), Stamax (SABIC). Used for automotive front-end carriers, battery trays, HVAC components, and household appliance frames.
