CHEMICAL STRUCTURE: 1.png

CHEMICAL NAME: N-TCyclohexy(thio)phthalimide

MOLECULAR FORMULA: C14H15O2SN

MOLECULAR WEIGHT: 261.34

CAS NO.: 17796-82-6

 

PROPERTIES:

White crystal/granule. Density is 1.25-1.35.

Soluble in acetone, benzene, toluol, diethyl ether, ethyl acetate, bot CCI4 and hot alcohol, slightly soluble in gasoline. Insoluble in derosene and water.

 

APPLICATION:

Pre-vulcanisation inhabitor. Provide predictable scorch control in most sulphur valcanisation. Improved cost performance through marginal stock recovery, single-stage mixing, higher processing and/or curing temperatures, activity is linear and higher than most retarders. May cause bloom above 0.5phr.

It is anti-scorching agent for both natural and synthetic rubber.
