Ethylene Propylene Diene Monomer (EPDM)
Description
Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber widely used for outdoor, automotive, roofing, and sealing applications. It is known for its excellent resistance to weathering, ozone, UV radiation, heat, and water. EPDM remains flexible over a wide temperature range and performs well in both hot and cold environments. Because of its strong resistance to aging and environmental exposure, it is commonly used in seals, gaskets, hoses, roofing membranes, electrical insulation, and automotive weatherstripping. However, EPDM has poor resistance to oils, fuels, and many hydrocarbon solvents, so it is not suitable for applications involving petroleum-based fluids.
