Problems solved by technology

[0002] Nitrile rubber is an elastomer synthesized by emulsion polymerization from butadiene and acrylonitrile monomers. Its molecular chain contains unsaturated double bonds and polar groups—CN, so it has excellent oil resistance and Excellent physical and mechanical properties, widely used in many fields such as machinery industry, vehicles, etc., however, its strength cannot meet the increasingly stringent industrial requirements. Therefore, a high-strength rubber is synthesized by adding other types of rubber or modifying it Nitrile rubber is essential
