Properties: gray-white or light yellow powder (granules), slightly bitter, non-toxic. Specific gravity 1.45-1.54, melting point above 170 °C, soluble in chloroform, slightly soluble in benzene and ethanol, carbon tetrachloride at room temperature, insoluble in gasoline, water and ethyl acetate. Stable storage.
Uses: natural rubber and a variety of synthetic rubber accelerators, can produce flat and medium speed vulcanization, high vulcanization temperature, significant after-effects, will not early vulcanization, safe operation, easy to disperse, no pollution, vulcanized rubber aging resistance. This product alone uses a slow vulcanization rate, usually used in conjunction with thiuram, dithiocarbamate, aldehyde amines, guanidine accelerators, and is an excellent anti-scorching agent for G-type neoprene. It is mainly used in the manufacture of tires, hoses, rubber shoes, adhesive tapes and other general industrial products. In neoprene, it can also act as a plasticizer or delaying agent.
Packing: 25kg plastic woven bag, paper-plastic composite bag, kraft paper bag, or container plastic woven bag.
Storage: Should be stored in a cool, dry, well-ventilated place. The packaged crystal production should be protected from direct sunlight and is valid for 2 years.
