Application:
MMB is be used for NR and SR. MMB has a synergistic effect with other antioxidants. MMB can get good heat resistance. MMB can also be used as vulcanization accelerator and rubber heat agent for CR.
MMB is easy to disperse in the rubber, but the solubility is not big. MMB is not discoloring in the sunlight, slight pollution. MMB can not only be used for white and light-colored products, but also be used for rubber wire and cable, conveyor belt, tape, rubber shoes etc, but MMB is not suitable for food contact rubber products.
