PROPERTIES:
White powder/granule. Density is 1.25-1.35. Soluble in acetone, benzene, toluol, ethyl acetate, hot CCl4 and hot alcohol, slightly soluble in gasoline, insoluble in kerosene and water.
APPLICATION:
PVI can prevent early vulcanizing in glue processing, Improving safety. At the same time significantly improve the storage stability of the glue, preventing natural vulcanization phenomena.
In NS, M, DM, CBS, semi-effective or efficient systems, to improve the plastic materials capability. No foam, pollution and other adverse effects.
Mainly use for natural and synthetic rubber, particularly with sulfenamide accelerators composing a good sulfuration system
