EPDM (Ethylene Propylene Diene Rubber) vs PEEK GF30
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.
PEEK GF30
PEEK with 30% short glass fiber reinforcement. Dramatically increased stiffness (E-Mod 11 GPa vs 4.1 unfilled) and strength (UTS 160 vs 100 MPa) with reduced elongation and creep. Maintains PEEK's chemical resistance and high-temp capability (continuous 250°C). Trade names: Victrex 450GL30, TECAPEEK GF30 (Ensinger), KetaSpire GF30 (Solvay). Used for structural brackets, pump housings, valve seats, bearing cages, and semiconductor wafer handling where higher stiffness than unfilled PEEK is needed.
