5-Ethylidene-2-norbornene

5-Ethylidene-2-norbornene is a cyclic olefin used as a comonomer in the synthesis of ethylene propylene diene monomer (EPDM) rubbers. It plays a crucial role in enhancing the cross-linking density and thus the mechanical properties of the final polymer. This product is widely utilized in the automotive industry for applications such as weather stripping, seals, and hoses, where its excellent heat, ozone, and chemical resistance are highly valued.
