Predispersed Rubber Chemical MBI-80

Identification:

Chemical Name: 2-Mercaptobenzimidazole

Synonym: Pre-Dispersed Polymer Bound Chemical MBI-80;Antioxidant MBI (MB)

CAS: 583-39-1

EINECS: 209-502-6

Molecular Formula: C7H6N2S

 

Properties: MBI synergistic effects in combination with other antioxidants. Effect of antioxidants combined with MBI is usually better than that alone. It is a moderate non-staining antioxidant especially for ultra fast accelerator contained rubber compounds and heat-resistant rubber compounds with no S but TMTD. It can activate rubbers with no S but TMTD. MBI with CBS, MBT or thiurams, dithiocarbamate is an anti-scorcher and can improve processing safety and stability of rubber compounds in storage.
