Application of 5-Ethylidene-2-norbornene CAS 16219-75-3
The vulcanization speed of Bide rubber is faster than that of other third monomers, which can overcome the shortcomings of slow vulcanization speed of ethylene-propylene-ethylene-propylene rubber.
It also has ozone resistance, chemical resistance (solvents, acids, alkalis, etc.), discharge resistance, and water vapor resistance.
Therefore, it can be used as a modified material for building materials such as rubber products, waterproof boards, and impact-resistant plastics around the engine.
