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.
