etüleenpropüleenkummi

Etheleenpropüleenkummi, often abbreviated as EPDM, is a synthetic rubber known for its excellent resistance to weathering, ozone, UV radiation, and heat. It is a terpolymer, meaning it is composed of three different monomers: etheleen, propüleen, and a diene monomer. The presence of the diene monomer allows for vulcanization, a process that cross-links the polymer chains to create a durable and elastic material.

EPDM rubber exhibits good electrical insulation properties, making it suitable for use in electrical applications. It also demonstrates resistance to polar solvents and steam. However, it has poor resistance to oils and petroleum-based products. Its flexibility at low temperatures is also a notable characteristic.

Common applications for EPDM include automotive parts such as hoses, seals, and weatherstripping, as well as roofing membranes, window gaskets, and electrical insulation. It is also used in various industrial seals, gaskets, and diaphragms where resistance to environmental factors is critical. The versatility and durability of EPDM have made it a widely used elastomer in numerous industries.
