Usage: A common organic chemical product, mainly used as an anti-polymerization agent in organic polymerization, it is used to prevent the production, separation, refining, storage or transportation of olefin units in the process of self-polymerization, control and regulate the degree of olefin and its derivatives in organic synthesis reaction. Storage: It is easy to absorb moisture. It should be stored in airtight and dry conditions and protect against high temperature. The package should be kept intact. Avoid co-stacking with acidic substances. Package : 25kg/bag or 25kg/carton
