EPDM (Ethylene Propylene Diene Rubber) vs PE-HD
Side-by-side chemical composition and mechanical property comparison.
Overview
EPDM (Ethylene Propylene Diene Rubber)
Ethylene propylene diene monomer rubber β 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. Ο 0.85-1.3 (lightest common rubber). Used for automotive door/window seals, roofing membranes, radiator hoses, HVAC gaskets, and pond liners.
PE-HD
High Density Polyethylene β the highest-volume plastic globally (>30M tons/year). Linear chains with minimal branching give higher density and strength vs LDPE. Excellent chemical resistance, FDA/food-safe, very low moisture absorption, and good impact resistance down to -30Β°C. Used for pipes, bottles, containers, fuel tanks, cutting boards, playground equipment, and geomembranes.
