Accelerator D（DPG）

It is mainly used as medium speed accelerator for natural rubber and synthetic rubber. It is commonly used as an active agent of thiazole, thiuram and hypoiodoyl accelerators. When used in combination with accelerators DM and TMTD, it can be used for continuous vulcanization. When the second accelerator of thiazole accelerator is used, the aging resistance of vulcanizate decreases, so appropriate antioxidant must be added. In chloroprene rubber, the product has the functions of plasticizer and plasticizer. This product is not suitable for white or light colored products and rubber products in contact with food. It is mainly used to manufacture tires, rubber plates, soles, industrial products, hard rubber and thick wall products. The dosage as the second accelerator is 1-2 phr, and the general dosage as the second accelerator of thiazole accelerator is 0.1-0.5 phr. Chromium tyrodiphenylguanidine, a derivative of diphenylguanidine, is a highly effective antirust agent. Diphenylguanidine is also used as plastic crosslinking agent, temperature indicating material, ore flotation agent, coating agent, polishing material agent, metal analysis agent and building material agent.
