Molecular Formula: C14H15O2SN
Molecular Weight: 261.3
white or yellowish crystal powder
Active substance(CTP content)
Loss on drying
Toluene insoluble substance
Melting point ºC
PVI disso es in acetone, benzene, toluene, ethyl ether, ethyl acetate as well as warm carbon tetra chloride, ethyl alcohol and heptanes: It slightly disso es in gasoline, but insoluble in kerosene and water.
It is a high effective pre-vulcanization inhibitor. It is applied in natural or synthetic rubber, NR, SBR, BR, LLR, CR, EPM, EPDM, NBR, with cure system consisting of sulfur and thiazole but mainly sulphenamide accelerator.
PVI can effectively prevent the rubber materials from scorching during processing, it makes that possible for extruder and calendar to run at high temperature and high speed, and improves capacity of the vulcanize. The product can also improve the storage stability of the rubber materials. Meanwhile, it has reclamation function for rubber materials that have been borne at high temperature or dangerous for scorching.
