EPDM (Ethylene Propylene Diene Rubber) vs PE-LLD (Linear Low-Density Polyethylene)
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.
PE-LLD (Linear Low-Density Polyethylene)
Linear low-density polyethylene — short-chain branching via copolymerization with alpha-olefins (butene, hexene, octene). Better puncture resistance, tear strength, and seal strength than PE-LD at same density. THE modern stretch wrap and food packaging film. Also used for agricultural film, liners, bags, and blown film. Largely replacing PE-LD in film applications.
