Chemical Structure

Specification:

ITEMS	Data
Appearance	White for light-yellow powders
Initial Melting Point ºC≥	140
Heating Loss %≤	0.5
Ash Content%≤	0.50
Residue on 100mesh(150μm)sieve %≤	0.50

Properties:
 Milk white and light-yellow powders, special smell. Specific gravity is 1.53-1.55. The melting point is more than 145ºC, 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 ºC).

Application:
 Super accelerator. At general temperature, it can cure rubber cement and lates. The critical temperature is 100ºC. The vulcanizing temperature is not more than 110ºC, 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.
