TBBS is a post-effective accelerator for natural rubber, paraben rubber, isoamyl rubber, butyl rubber and recycled rubber, especially for carbon black rubber containing strong alkalis. It is safe at operating temperature, with strong anti-scorch, fast curing speed, and high tensile strength, and can improve the use ratio of synthetic rubber. With low toxicity and high efficiency, it is an ideal substitute for NOBS, with excellent overall performance, and is known as a standard accelerator. It is widely used in the production of radial tires. It can be used with aldehyde amine, guanidine, and thiuram accelerators, and when used with anti-coke agent PVI, it forms a good vulcanization system. It is mainly used in the manufacture and production of tires, rubber shoes, rubber tubes, tapes and cables.


It should be stored in a single layer in a cool, dry and well-ventilated place. Packaged products should be protected from direct sunlight, overlapping piles will cause abnormal compression or particle breakage. High humidity or high temperature will cause the product to decompose. Valid for 1 year.
