Uses    As a multifunctional rubber additive, it can be used as a vulcanizing agent in the rubber processing process, as a vulcanizing agent for peroxide systems, and as a scorch retarder and tackifier. It is suitable for general purpose rubber. Suitable for special rubber and rubber and plastic systems. In natural rubber, it can prevent vulcanization and reversion, improve heat resistance, reduce heat generation, anti-aging, and improve rubber and cord adhesion and vulcanization modulus. It can be used in rubber such as load tire rubber and buffer layer to solve the shoulder-space problem of skew truck tires. It can also be used for large-size thick products of natural rubber and various rubber sundries. This product is used in special rubber such as neoprene, chlorosulfonated polyethylene rubber, styrene butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, bromobutyl rubber, silicone rubber and rubber and plastic. As an auxiliary vulcanizing agent, it can significantly improve the crosslinking performance and improve the heat resistance. It is suitable for high-temperature vulcanization systems, and it is very obvious to reduce the compression set. It can also reduce the amount of peroxide and prevent the scorch of the rubber during the code processing. , to improve the bonding strength of the rubber and cord and metal.
