Basic Information

Accelerant M is an ultra-fast Accelerant of natural rubber and has the effect of a plasticizer. The low critical temperature of vulcanization can easily cause early curing of the rubber. It can be used alone or in combination with other Accelerant s. Apply to tires, rubber shoes, industrial rubber products. Due to its bitter taste, it is not suitable for rubber products for the food industry. Can be used as a vulcanization retarder in neoprene. This product and its derivatives are the most important Accelerant s.
