Generally speaking, the higher the molar mass, the better the physical and mechanical properties of the vulcanized rubber, but its processability and fluidity will decline, and the speed of "powder intake" (filler mixing into raw rubber) will slow down. When processing molded compound rubber, raw rubber with a high molar mass (>600,000) ti yan ni gbogbogbo.
