2-Mercaptobenzimidazole (CAS: 583-39-1) Applications
2-Mercaptobenzimidazole is used as an antioxidant for natural rubber, diene synthetic rubber, and latex.
Applied to polyethylene, 2-Mercaptobenzimidazole provides protection against oxidation, weathering, and static aging. It also effectively protects against copper damage and overcomes the adverse effects of oversulfurization during crystal vulcanization.
2-Mercaptobenzimidazole can be used alone or in combination with other antioxidants (such as DNP, AP, and other non-polluting antioxidants) to achieve significant synergistic effects.
When used alone, the dosage is generally 1-1.5 parts. Exceeding 2 parts may cause frosting. The dosage in latex foam rubber is 0.5 parts.
