MBS is light yellow or orange crystal/granule. Density is 1.34-1.40.No poison, with a little bit odor of ammonia.Soluble in benzene, acetone, chloroform.Insoluble in water, acid and alkali with lower concentration.
MBS is an excellent delayed accelerator. Its performance is similar to CZ with better scorch safety.
Widely used in NR, IR, SBR, NBR and EPDM.
Mainly used in manufacture of tyres, shoes and belts.
Can be used alone or with other vulcanization accelerators such as thiurams guanidines and dithiocarbamates to improve the activity.
