Typical Properties 

Rubber Accelerator TBBS is white powder.The density is is soluble in Chloroform, Benzene, and Alcohol.and insoluble in water, gasoline, and acid/alkali with lower concentration.


In natural and synthetic rubber tire compounds; Accelerator TBBS is normally used alone or with small quantities of secondary accelerators in combination with sulfur. 

It is also used in industrial rubber products with higher levels of secondary accelerators, such as the TMTD to obtain faster vulcanization cycles and improved aging resistance

It may also be used in EPDM and NBR compounding as the primary accelerator, giving good scorch delay and fast cure rates.

In comparison to Rubber Accelerator CBS it displays a slightly longer scorch delay and is slightly more active. In NR, SBR, BR and blends, Rubber Accelerator TBBS, when used at a 10% lower level, will give equal modulus to China Rubber Accelerator CBS supplier and Rubber Accelerator NOBS.
