Product Data

The density is 1.45-1.54. Soluble in chloroform, partly soluble in benzene, ethanol, CCl4 insoluble in gasoline, water and ethyl acetate. Good storage stability.


The accelerator for natural rubber and many kinds of synthetic rubber can produce flat and medium speed vulcanization, higher vulcanization temperature, significant after-effects, no early vulcanization, safe operation, easy dispersion, no pollution, and aging resistance of vulcanized rubber. It is used alone with slow vulcanization speed, usually used with Tyuram, dithiocarbamate, aldehyde amine and guanidine accelerators, and is an excellent anti-scorching agent for G-type neoprene. It is mainly used in the manufacture of general industrial products such as tires, hoses, rubber shoes and rubber cloth. It can also play the role of plasticizer or delaying agent in neoprene.


It should be stored in a cool, dry and well-ventilated place. Packaged products should be protected from direct sunlight and are valid for 2 years.
