Rubber Accelerator NOBS is the light yellow or orange crystal (granule). No poison with a little odor of ammonia. The density is 1.34-1.40.It soluble in benzene, acetone. chloroform, insoluble in water, acid, and alkali with lower concentration
NOBS is an excellent delayed accelerator. The performance is similar as CZ with better scorch safety. It is widely used in NR, IR, SBR, NBR and EPDM. Can be used alone or with other vulcanization accelerators such as thiurams, guanidines and dithiocarbamates to improve the activity. Mainly used in manufacture of tires, shoes and belts
