Sunnyjoint Accelerator M

- Sep 27, 2018-

It is an overspeed accelerator for natural rubber and has the effect of plasticizer. The critical temperature of vulcanization is low, which tends to cause early vulcanization of the rubber compound. It can be used alone or in combination with other accelerators. Suitable for tires, rubber shoes, industrial rubber products. Due to the bitter taste, it is not suitable for rubber products used in the food industry. It can be used as a vulcanization retarder in neoprene. This product and its derivatives are the most important promoters.
