EPDM (Ethylene Propylene Diene Rubber) vs TPU (Thermoplastic Polyurethane)
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.
TPU (Thermoplastic Polyurethane)
Thermoplastic polyurethane elastomer — bridges the gap between rubber and rigid plastics. Exceptional abrasion resistance, high elongation (300-700%), and good oil/grease resistance. Available in wide hardness range (60 Shore A to 74 Shore D). Ester-based: better oil resistance. Ether-based: better hydrolysis/microbial resistance. Major trade names: Elastollan (BASF), Desmopan/Texin (Covestro), Estane (Lubrizol). Used for seals, hoses, cable jackets, shoe soles, phone cases, wheels/rollers, and 3D printing filament.
