  • The reasons that affect rubber scorching

    Rubber scorching is a type of advanced vulcanization behavior, which refers to the phenomenon of early vulcanization that occurs in various processes before vulcanization (rubber refining, rubber storage, extrusion, rolling, forming). Therefore, it can also be called early vulcanization. Rubber s...
