Scorch Retarder PVI(CTP) - 80 , Beige Granule , Used In Natural And Synthesis Rubber?.

Recommendations?and?Applications:

Scorch?retarder?CTP?prevent?rubber?from?early?vulcanization?in?manufacturing?process ,?

improve??processing?safety ,?with?almost?no?influence?on?curing?rate?and?physical?properties?

of?vulcanizates.?

CTP?significantly?improve?high?temperature?and?high?speed?processability?of?the?rubber?

in?the?calender?and?extruder ,?increase?production?capacity?of?vulcanizing?machine ,?

improve?storage?stability?of?the?compound,?avoid?self-vulcanization?during?the?storage.?

Scorch?retarder?CTP?can?be?used?along?with?accelerator?NS ,?M ,?DM ,?CBS?and?effective?or?

half?effective?vulcanization?system ,?improve?compounds’?performance,?without?foaming ,?

contamination?and?other?adverse?side?effect.?

Mainly?used?in?natural?rubber ,?synthesis?rubber,?especially?used?along?with?sulfonamide?

to?form?a?good?vulcanization?system.?
