More Information
Summary:The invention discloses a filler opening seal ring material for an automobile braking master cylinder and a process for manufacturing a seal ring. The filler opening seal ring material for the automobile braking master cylinder is prepared by proportioning the following materials in parts by weight: 80-120 parts of ethylene propylene rubber (EPR), 4-6 parts of active agent, 1-3 parts of lubricant, 2-4 parts of acid-base balance agent, 1-3 parts of antiager, 2-4 parts of vulcanizer and 25-35 parts of inorganic filler. The process for manufacturing the seal ring comprises the following steps: mixing and shaping the materials, carrying out primary vulcanization, punching, trimming and carrying out secondary vulcanization to produce the filler opening seal for the automobile braking master cylinder, wherein the filler opening seal ring has high intensity, low compression deformation, tear resistance, braking fluid corrosion resistance and excellent high and low temperature resistance, thus having high production
