This product is a delayed action accelerator of natural rubber, butadiene rubber, isoprene rubber and styrene butadiene rubber and reclaimed rubber, especially suitable for containing carbon black rubber strong alkaline. Safe operating temperature, anti scorch resistance, fast curing, high tensile strength, can improve the use ratio of synthetic rubber. High efficiency and low toxicity, NOBS is the ideal substitute, has excellent comprehensive properties, known as the standard accelerator. Widely used in the production of radial tires. The same, guanidine aldehyde amine, thiurams accelerator, and the antiscorching agent PVI was used, a good curing system. Mainly used for manufacturing tires, rubber shoes, rubber hose, rubber belt, cable.
