RUBBER ACCELERATOR TBBS SPECIFICATIONS
Chemical Name : N-tert-butyl-2-benzothiazole sulfenamide
Molecular Formula : C11H14N2S2
Characteristics: Gray or light yellow in color, with a bitter taste and a slight odor. Specific gravity: 1.26-1.32, soluble in ethanol, carbon tetrachloride, acetone, benzene, carbon disulfide, chloroform; nearly insoluble in gasoline and insoluble in water. Does not absorb moisture.
Application: The main classes of peroxide cross-linking agents are dialkyl and diaryl peroxides, peroxyketals, and peroxyesters. Other vulcanizing agents include amine compounds for fluorocarbon rubbers, metal oxides (especially zinc oxide for chlorinated rubbers like chloroprene rubber), and phenol-formaldehyde resins for producing heat-resistant butyl rubber vulcanizates. In the rubber industry, an accelerator is added with a curing agent to speed up vulcanization. Accelerators contain sulfur and nitrogen compounds such as benzothiazole and thiocarbamylid derivatives. Popular accelerators include sulfenamides (as delayed-action accelerators), thiazoles, thiuram sulfides, dithiocarbamates, and guanidines.
Storage: Keep the container tightly closed, store in a cool, well-ventilated area. The recommended maximum storage life, under normal storage conditions, is 1 year.
