EthylenpropylenCopolymere
EthylenpropylenCopolymere, often abbreviated as EPDM (Ethylene Propylene Diene Monomer) rubber, are a class of synthetic rubbers derived from ethylene and propylene. These copolymers are formed by polymerizing ethylene and propylene monomers, often with a third diene monomer to introduce unsaturation, which allows for sulfur vulcanization. The ratio of ethylene to propylene in the copolymer can be varied to tailor the material's properties. Higher ethylene content generally leads to improved low-temperature flexibility and tensile strength, while higher propylene content can enhance heat resistance.
EPDM rubber exhibits excellent resistance to weathering, ozone, UV radiation, and heat. It also possesses good
