PROPERTIES:
White powder/granule.The density is 1.26-1.32.it is soluble in Chloroform, Benzene, and Alcohol.and insoluble in water, gasoline, and acid/alkali with lower concentration.
APPLICATION:
In natural and synthetic rubber tire compounds;TBBS is normally used alone or with small quantities of secondary accelerators in combination with sulfur.
TBBS 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.
Widely used in all sorts of rubber products and tires, especially the meridian tires.
The product is an excellent delayed accelerator with more delayed action and great curing rate and other advantages.
