Properties: white powder, soluble in diethyl ether, benzene, carbon disulfide, chloroform, tetrachlorethylene, carbon tetrachloride and dichloromethane; insoluble in gasoline, methanol, water and diluted alkali. It can be stored stably.
Application: It is super accelerator for natural rubber, synthetic rubber and latex. At the temperature over 100°C, the vulcanization is fast. At the temperature lower than 120°C, the plateau cure is medium, while at the temperature is over that, the plateau cure is low. The most appropriate temperature is 95-110°C. Since the product is highly soluble in organic solvent, it is generally used in cold vulcanization rubber cement.
Package: plastic woven bag or plastic film bag lined kraft laminated bag, 25kg/bag.
