Antioxidant MBI (2-Mercaptobenzimidazole)
2-Mercaptobenzimidazole (MBI) is a non-staining, non-discoloring antioxidant that provides good protection against thermal oxidation and catalytic degradation induced by heavy metal ions. It is widely used in light-colored and white rubber articles where staining must be avoided, and serves as an effective copper-ion deactivator. MBI is often blended with other antioxidants for synergistic protection in EPDM, NBR, and natural rubber.
