Description

2-Cyclohexyl-4,6-Di(α-Methylbenzyl)Phenol is a high-purity, sterically hindered phenolic compound, primarily valued for its exceptional performance as an antioxidant and stabilizer in demanding polymer systems. Its molecular structure provides superior resistance to thermal and oxidative degradation, making it a critical additive for extending the service life and maintaining the properties of high-performance materials. This product is essential for manufacturers in the polymer, rubber, and specialty chemical industries seeking reliable protection for their formulations against environmental stressors.

Application

• Polymer Stabilizer: A primary antioxidant in polyolefins (e.g., PP, PE), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation during processing and end-use.
• Rubber Additive: Used in the production of tires, seals, and industrial rubber goods to enhance aging resistance and durability.
• Lubricant & Fuel Additive: Functions as an antioxidant in industrial lubricants, greases, and fuels to inhibit sludge formation and viscosity increase.
• Adhesive & Sealant Formulations: Improves the long-term stability and performance of high-quality adhesives and sealants.
• Synergistic Stabilizer Systems: Often used in combination with secondary antioxidants (e.g., phosphites, thioesters) for enhanced stabilization effects.
• Intermediate for Specialty Chemicals: Serves as a key building block in the synthesis of more complex antioxidant and stabilizer molecules.

Quality Control

Our 2-Cyclohexyl-4,6-Di(α-Methylbenzyl)Phenol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure it meets precise specifications for use in sensitive polymer and chemical applications. Certificates of Analysis (COA) documenting all critical quality parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve product integrity. Keep away from strong oxidizing agents.
