The raw rubber that has been plasticized is re-refined on the machine, softened by heating, and blended with other polymers. 2 plus compounding agent. Generally, a softener, stearic acid, etc. are added first, and then a powder and carbon black are added (carbon black can also be separately mixed with a raw rubber as a masterbatch in advance). Sulfur is usually added at the end of the mixing or after the second re-refining of the compound. 3 mix evenly and remove the slice. Once all the ingredients have been added, continue to re-mix to evenly mix and remove the slice.
