EPDM (Ethylene Propylene Diene Rubber) vs PA12 (Nylon 12)
Side-by-side chemical composition and mechanical property comparison.
Overview
EPDM (Ethylene Propylene Diene Rubber)
Ethylene propylene diene monomer rubber — THE outdoor/weather elastomer. Saturated backbone gives outstanding ozone, UV, and weathering resistance. Excellent resistance to steam, hot water, and polar solvents. NOT resistant to oils/fuels (opposite of NBR). Good electrical insulation. ρ 0.85-1.3 (lightest common rubber). Used for automotive door/window seals, roofing membranes, radiator hoses, HVAC gaskets, and pond liners.
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.
