RUBBER ACCELERATOR TBBS SPECIFICATION

Chemical Name               : N-Tertiarybutyl-2-benzothiazole-sulfenamide

Molecular Formula          : C11H14N2S2

Structural Formula

Properties: Grey or light yellow in color with bitter taste and slight odor. Specific gravity: 1.26-1.32, Soluble in ehanol, carbon tetrachloride, acetone, benzene, carbon disulfate, chloroform; Hardly soluble in gasoline and insoluble in water. It is not hygroscopic.

Application: The principal classes of peroxide cross-linking agents are dialkyl and diaralkyl peroxides, peroxyketals and peroxyesters. Other vulcanizing agents include amine compounds for the cross-linking of fluorocarbon rubbers, metal oxides for chlorine-containing rubbers (notably zinc oxide for chloroprene rubber) and phenol-formaldehyde resins for the production of heat-resistant butyl rubber vulcanizates. Accelerator, in the rubber industry, is added with a curing agent to speed the vulcanization. Accelerators contain sulfur and nitrogen like derivatives of benzothiazole and thiocarbanilides. The popular accelerators are sulfenamides (as a delayed-action accelerators), thiazoles, thiuram sulfides, dithocarbamates and guanidines.

Storage :Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 1 year when stored under normal conditions.
