EPDM (Ethylene Propylene Diene Rubber) vs PC (Polycarbonate)
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.
PC (Polycarbonate)
Polycarbonate — the transparent high-impact engineering plastic. Amorphous with outstanding impact strength (virtually unbreakable at room temp), optical clarity (~90% light transmission), and good heat resistance (Tg 145-150°C). Trade names include Lexan (SABIC), Makrolon (Covestro). Used for safety glazing, machine guards, automotive headlamp lenses, CDs/DVDs, riot shields, and electronic housings.
