Key Specifications

Industrial Applications

This antioxidant is extensively utilized across multiple sectors due to its versatile compatibility. It is particularly effective in protecting polyolefins, engineering plastics, and synthetic rubbers from thermal and light-induced oxidation. Common substrates include Polyamide (PA), Polyethylene (PE), Polypropylene (PP), Polyvinyl Chloride (PVC), ABS, SBS, and various adhesive formulations. The chemical stability allows it to withstand processing temperatures up to 200℃ without decomposition, ensuring consistent performance during extrusion and molding processes.

Performance Advantages

• Non-Discoloring Properties: Unlike some traditional antioxidants, BBMC does not cause frosting or discoloration, making it perfect for white or light-colored finished products.
• Low Volatility: The compound exhibits minimal volatility even at elevated temperatures, reducing loss during high-heat processing.
• Synergistic Effects: When combined with phosphite or thioester antioxidants, it demonstrates enhanced synergistic protection, extending the service life of the material.
• Low Toxicity: Formulated to meet safety standards, it poses low toxicity risks during handling and application.
