MBT , Pre-dispersed Accelerator , Light Yellow Granule , Used In Tires .

Recommendations?and?Applications:

MBT?is?used?as?an?acid?accelerator?and?a?medium?fast?primary?accelerator ,?

a?muti-function?accelerator?with?a?long?flat?vulcanizing?period ,?

impacts?good?physical?and?mechanical?properties?of?vulcanizates.?

It?is?a?anti-scorching?agent?of?vulcanization?system?absence?of?sulfur ,

used?ad?curing?delay?agent?in?CR?rubber.?

Alkaline?accelerator?like?aldehyde?amine?and?guanidine ,?

thiuram?and?dithiocarbamate?salts?accelerator?would?activate?MBT.??

Its?accelerative?temperature?is?low?and?easily?be?dispersed?with?lower?pollution.

Mainly?used?in?the?manufacture?of?tires ,?tubes ,?rubber?soles ,?rubber?belts?and?hoses?etc ,

to?vulcanize?IR ,?NR ,?SBR ,?NBR ,?HR?and?EPDM ,?but?on?use?in?food?industry.

Used?as?primary?accelerator?in?NR?and?SBR ,?add?1.0~2.0?PHR?MBT?along?with?2.0~3.0?PHR?sulfur.

To?vulcanize?IIR,?add?0.5~1.0?PHR?MBT?along?with?0.5~1.5?PHR?TMTD?and?1.0~2.0?PHR?sulfur.

Advantages:

MBT-80?is?pre-dispersed?in?rubber?binder,?with?no?dust?pollution ,?

is?environment?friendly?and?good?for?worker’s?health.?

Masterbatch?MBT-80?granules?don’t?stick?to?each?other?at?room?temperature ,

which?make?is?easier?to?disperse?in?rubber?compound ,?with?no?weight?loss.

It?has?good?compatibility?with?rubber ,significantly?improve?the?mixing?efficiency ,?

reduce?energy?consumption.
