Ethylene Propylene Diene Monomer (EPDM) is a saturated, non-polar synthetic elastomer derived from ethylene, propylene, and a small amount of diene (commonly ENB or DCPD) that provides crosslinking sites during vulcanization. EPDM is best known for its exceptional resistance to heat, ozone, steam, weathering, and polar fluids, making it one of the most stable and long-lasting elastomers available for outdoor and high-temperature environments.
Our EPDM compounds are formulated for long-term sealing performance in applications where water, steam, glycol, or weather exposure would degrade most hydrocarbon rubbers. EPDM elastomers combine excellent aging stability, low compression set, and outstanding flexibility across a wide temperature range, providing durable sealing and vibration isolation in harsh outdoor or high-moisture environments.
