What is EPDM Rubber?
EPDM Rubber (Ethylene Propylene Diene Monomer) is a synthetic elastomer formed from the polymerization of three main monomers: Ethylene, Propylene, and Diene Monomer. Its unique chemical structure provides exceptional molecular stability against environmental degradation. This material belongs to the specialty rubber family with performance advantages in extreme conditions.
In terms of raw materials, EPDM is produced through controlled polymerization with added carbon black, plasticizers, and special additives. This composition results in a highly flexible material while maintaining tensile strength up to 17 MPa. Key physical characteristics include density of 0.85-1.20 g/cm³ and hardness of 40-90 Shore A.
Generally, EPDM is known as the material with the best thermal resistance in its elastomer class (-50°C to +150°C), and has excellent chemical resistance against water, steam, alkalis, and polar solvents. Learn more on our material specifications page.
Product Functions
Sealing & Gasketing: Primary solution for automotive gaskets, door/window seals, and chemical tank gaskets with pressure handling up to 25 bar. Effectively prevents leaks of air, water, and corrosive fluids.
Electrical Insulation: Widely used as insulators for high-voltage cables and electrical components due to its superior dielectric properties (resistivity >10¹⁵ Ω·cm).
Environmental Protection: Roofing membrane applications for stadium roofs and industrial buildings, as well as weather-resistant layers for construction.
Cooling Systems: Key component for radiator hoses, automotive AC O-rings, and industrial cooling machine seals.
Medical Devices: Safe material for drug vial septums and non-implant medical equipment components.
