The present invention makes public a type of acrylate rubber materials used in crankcase ventilation pipes, which belongs to the technological field of rubber and has the following characteristic qualities: acrylate rubber PA 402L, 40-70; acrylate rubber PA 402H, 30-60; stearic acid, 1-2; age resister Dusantox 86, 2-3; processing agent Vanfre VAM, 1-2; carbon black N330, 25-45; carbon black N550, 10-30; potassium stearate, 0.2-0.5; sodium stearate, 1-4; brimstone, 0.1-0.3. The oil resistance of this acrylate rubber made by the above mentioned materials is superior than the now commonly used acrylate rubber's, its heat resistance corresponds to ethylene acrylate rubber's and its cost is cheaper. |
