Properties:

A little bitter taste. Specific gravity: 1.45-1.54. Soluble in chloroform, slightly soluble in benzene, ethyl alcohol and carbon tetrachloride, insoluble in gasoline, water and ethyl acetate, stable in storage. 
Application:

Give flat, moderately fast cures in NR, IR, SBR, NBR, EPDM, IIR. Can be used alone as delayed action accelerator, normally with accelerators of guanidines & thiurams. Mainly used in manufacture of tires, tubes, shoes, rubber cloth and other technical rubber goods, especially those special-shaped products demanding high intensity. Exhibits better scorch safety than MBT, non-staining/ non-discoloring in light-color or colorfull stocks. However, because of the bitterness of the product after vulcanization, it is not recommended to apply it to beverage and food containers. This product can also be acted as a plasticiser/ retarder in CR. 
Package:
