Properties:

Milk white and light-yellow powders, special smell. Specific gravity is 1.53-1.55. The melting point is more than 145℃, but it will be decomposited. Soluble in carbon disulfide, a little soluble in benzene, toluene, alcohol, ethylene dichloride, carbon tetra-chloride, not easy to soluble water. It needs to be stored at lower temperature (below 10℃).

Application:

Super accelerator. At general temperature, it can cure rubber cement and lates. The critical temperature is 100℃. The vulcanizing temperature is not more than 110℃, otherwise, it will be decomposited. Since it will reduce the stability of lates, it is nesseary to add the other stabilizers in lates. In self-vulcanization rubber cement, it is suitable to mix with diethylammonium diethyldi-thiocarbamate. It is not only used in producing latex dipping products and rubber cements, but rubber silk and waterproof knit goods. The general use level is 1-2.5.

Package:

25kg N.W./bag, in plastic fabric laminated kraft bags lined with plastic bags.
