Product Application of 2,2'-Azobis(2-methylpropionitrile) CAS#78-67-1

As an initiator for the polymerization of vinyl chloride, vinyl acetate, acrylonitrile and other monomers, and also as a foaming agent for rubber and plastics, the dosage is 10% to 20%. This product can also be used as a vulcanizing agent, pesticide and intermediate in organic synthesis. This product is a highly toxic substance, with an oral LD50 of 17.2 to 25 mg/kg for mice. The organic cyanide released by thermal decomposition is highly toxic to the human body.
