Properties:White powder(Granule). Specific gravity: 1.25--1.35. Soluble in acetone, benzene, toluol, diethyl ether, ethyl acetate, hot CCl4and hot alcohol, slightly soluble in gasoline, insoluble in derosene andwater.
Application:PVI is used for the prevention of prevulcanization in most vulcanization system of sulphur. PVI has higher activity than most delay agents. Frosting will occur when its use level is higher than 0.5 pose.
Packing:
Storage:Stored in cool, dry and draughty place. Avoid direct sunlight.
