PA12 (Nylon 12) vs PPS GF40
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.
PPS GF40
Polyphenylene Sulfide with 40% glass fiber — the ultimate under-hood engineering plastic. Service to 240°C continuous, inherently V-0 flame resistant without additives, near-zero moisture absorption (<0.02%), exceptional chemical resistance (comparable to PEEK/fluoropolymers). Trade names include Ryton R-4 (Solvay), Fortron 1140L4 (Celanese), Tedur (INEOS), TECATRON GF40 (Ensinger). Used for automotive water pump impellers, thermostat housings, EGR valves, LED reflectors, and semiconductor wafer carriers.
