Can the core rubber of different manufacturers be mixed?

It is not recommended to mix skim rubber from different manufacturers because the formulations of skim rubber from different manufacturers are different. There are many kinds of compounding agents in rubber, and some will have an interactive reaction. In the formula of the same manufacturer, there will be no compounding agents with adverse interaction reactions, but the formulations of different manufacturers vary greatly, and the skim rubber of different manufacturers will be together. When used, there may be an interaction reaction of the compounding agent, which affects the use effect of the skim rubber.
