Description

2-Mercaptobenzimidazole Zinc Salt is a high-performance organometallic compound widely used as a critical antioxidant and stabilizer. Its primary value lies in its exceptional ability to protect materials from thermal degradation and oxidation, thereby significantly extending product lifespan and performance. This product is essential for manufacturers in the rubber, polymer, and lubricant industries seeking to enhance the durability and stability of their formulations.

Application

• Rubber Industry: Serves as a highly effective non-staining antioxidant and peptizer in the production of synthetic rubbers, latex, and rubber goods, preventing heat aging and flex cracking.
• Polymer Stabilization: Acts as a key additive in polyolefins (e.g., polyethylene, polypropylene) and other polymers to inhibit thermal-oxidative degradation during processing and end-use.
• Lubricant & Grease Additive: Functions as an antioxidant and anti-wear agent in industrial lubricants and greases, protecting against viscosity increase and sludge formation.
• Copper Corrosion Inhibitor: Used in metalworking fluids and industrial coolants to provide excellent protection against copper and copper alloy corrosion.
• Adhesive & Sealant Formulations: Incorporated to improve the heat resistance and long-term stability of adhesive and sealant products.
• Wire & Cable Insulation: A critical component in the stabilization of plastic and rubber compounds used for insulating wires and cables.
