Shape: white powder (granules).Specific weight 1.25-1.35. Soluble in acetone, benzene, toluene, ethyl ether, ethyl acetate, hot carbon tetrachloride, hot alcohol, slightly soluble in gasoline, insoluble in kerosene and water.

Usage: it can prevent the early vulcanization of rubber material in the processing process, improve the processing safety, but has little effect on the vulcanization speed and vulcanization properties.Because can effectively prevent coke, make calender, extruder high temperature and high speed operation is possible, and can effectively use strong vulcanizing active agent, improve the production capacity of vulcanizing machine, the total production capacity of the plant to improve.It can greatly improve the stability of rubber material in storage and prevent natural vulcanization during storage.Can be used with accelerators NS, M, DM, GBS and effective or semi-effective vulcanization systems to improve the performance of the rubber.This product has the regeneration and recovery effect for the rubber materials that have been subjected to high heat due to the season, operation and improper coordination, etc. Or the rubber materials that have the charred risk and cannot be further processed.No foaming, pollution and other adverse side effects.It is mainly used in natural rubber, synthetic rubber, especially when it is used with the accelerator of sulfonamide, forming a good vulcanization system.

Packing :25kg woven plastic bag, paper - plastic composite bag, kraft paper bag.

Storage: it should be stored in a cool, dry and well-ventilated place.The packaged products should be out of direct sunlight and valid for 2 years.
