EPDM (Ethylene Propylene Diene Rubber) vs PP-C (Polypropylene Copolymer)
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.
PP-C (Polypropylene Copolymer)
Polypropylene copolymer (random or block) — better impact resistance at low temperatures than PP homopolymer (PP-H). Random copolymer: excellent clarity for packaging. Block copolymer: high impact for automotive bumpers, containers, and household appliances. Trade names: Moplen (LyondellBasell), Hostalen (LyondellBasell). THE automotive interior/exterior polymer alongside ABS.
