Specifications

Rubber Chemicals-Antiscorching Agent CTP/PVI

Chemical Name: N-(cyclohexylthio)Phthalimide
Granular CTP with non-toxic wax can prevent the irritation, diminishes the losses during the operation, and assure the excellent dispersion.
Empirical Formula:C14H15O2SN
Molecular Weight:261.3
Chemical Structure:

Physical Form: White granule
Technical Parameters: 
Active substance(CTP): 77% by weight min.
