PVI dissolves in acetone, benzene, toluene, ethyl ether, ethyl acetate as well as warm carbon tetra chloride, ethyl alcohol and heptane: It slightly dissolves in gasoline, but insoluble in kerosene.
Usage;
It is high effective pre-vulcanization inhibitor. It is applied in natural or synthetic rubber, NR, SBR, ER, CR, EPM, EPDM, NBR with cure system consisting of sulfur and Thiazole but mainly Sulphennamide Accelerator.
PVI can effectively prevent the rubber materials from scorching during processing, it makes it possible for extrude and calendar to run at high temperature and high speed, and improves capacity of the vulcanizer. The product can also improve the storage stability of the rubber materials and keep them from natural vulcanization during storage. Meanwhile, it has reclaimaion function for rubber materials that have been borne at high temperature or dangerous for scorching.
