EPDMKautschuk
EPDMKautschuk, also known as EPDM rubber, is a synthetic elastomer based on ethylene, propylene and a non-conjugated diene monomer. It is produced by copolymerizing these components, with the diene providing crosslinkable sites for vulcanization. The resulting polymer offers excellent resistance to weathering, ozone and ultraviolet light, and it maintains flexibility at low temperatures. EPDM operates over a wide temperature range, typically roughly -50 to about 150 C depending on formulation, and it shows strong resistance to water, steam and many inorganic acids and bases. It also provides good electrical insulation and favorable dynamic properties for seals and gaskets.
EPDM is not well suited for exposure to most petroleum oils and fuels or many organic solvents;
Common applications include automotive weatherstrips, door and window seals, radiator and heater hoses, roof membranes, gaskets
Recyclability is limited because EPDM is a crosslinked elastomer, but devulcanization, crumb rubber processing and energy
