Vulcanization Anti Scorching Retarder CTP(PVI)
Chemical name: N-cyclohexyl thio phthalimidine

Molecular formula:C₁₄H₁₅O₂NS
Molecular weight:261.33
Structural formula:
Feature: The material is white or yellowish crystalline powder, 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 is insoluble in kerosene and water.
Uses:The material can be used in natural or synthetic rubber and can effectively prevent the rubber materials from scorching during processing, if makes if possible for extruder and calender 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.
Storage: In dry airiness place, avoid heat and moisture; it is the stable matter
