etylenpropylendienmonomergummi

Etylenpropylendienmonomergummi, often abbreviated as EPDM, is a synthetic rubber belonging to the elastomer family. It is a terpolymer, meaning it is synthesized from three different monomers: ethylene, propylene, and a diene monomer. The presence of the diene monomer in the polymer chain allows for sulfur vulcanization, a process that cross-links the polymer chains and gives EPDM its rubbery properties and elasticity.

EPDM is highly valued for its excellent resistance to weathering, ozone, and UV radiation. It also exhibits good thermal stability, capable of withstanding a wide range of temperatures, and is resistant to steam and hot water. Furthermore, EPDM demonstrates good electrical insulation properties and is resistant to many polar solvents and chemicals, such as dilute acids and alkalis. However, it has poor resistance to petroleum-based oils and fuels.

Due to its favorable properties, EPDM finds widespread use in various applications. It is commonly employed in the automotive industry for seals, hoses, and weatherstripping. In construction, it is used for roofing membranes, window and door seals, and expansion joints. EPDM is also utilized in electrical insulation, appliance seals, and as a vibration damping material. Its durability and resistance to environmental factors make it a popular choice for outdoor and demanding applications.
