CTP(PVI)-80
Composition：80% N-cyclohexylthiophthalimide, 20%Carrier and dispersing agent
Appearance：Beige particles
Density：About 1.13g/cm3
Filtration（μm）：200
Description
This Rubber Masterbatch CTP-80 can prevent early curing of the rubber compound during processing and improve the processing safety, while it has almost no effect on the vulcanization rate and vulcanizate properties. For it can effectively prevent scorching, the high temperature and high speed operation of the calender and the extruder can be made possible, and the powerful vulcanization activator can be effectively used to increase the production capacity of vulcanization machine. This product has a rejuvenating effect for rubber which has been subjected to high temperatures due to seasons, handling, and improper operation, or a compound that can not be further processed with the risk of scorching.
Function
JXBHgran CTP-80 is a kind of antiscorching agent. It can delay NR and SR starting vulcanization time without affecting the overall curing time. It can also improve the processing safety without affecting the performance of vulcanized rubber with sulfonamide and thiazole accelerator used together. JXBHgran CTP-80 can significantly improve the storage stability and high temperature of unvulcanized rubber processing safety performance, and fully improve the production capacity of equipment. The use of the product will not cause contact contamination.
Dosage
0.2-2.0 phr.
Application
The product is mainly used for natural rubber and synthetic rubber which use sulfonamides or thiazoles as the main accelerator.
