Product Usage

As the third monomer, this product can be copolymerized with ethylene and propylene to obtain ethylene-propylene rubber. The vulcanization speed of Biide rubber is faster than 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.
