Problems solved by technology

[0002] EPDM rubber not only has excellent heat resistance, oxygen resistance, ozone resistance, weather resistance and aging resistance, but also has good chemical resistance, electrical insulation performance and low temperature performance. In addition, it also has low density and high filling property. and hot water resistance, etc., have been widely used in wire and cable, auto parts, heat-resistant hoses, home appliances and other fields, but EPDM rubber also has the disadvantages of poor oil resistance and slow vulcanization speed. In addition, as an organic polymer material, has a flammable defect
Simple EPDM materials can no longer fully meet the requirements, and its products often have defects such as insufficient oil resistance, poor flame retardancy, unsatisfactory heat resistance and aging resistance during use, and need to be improved. sex
