Description

2,6-Dioctadecyl-p-cresol is a high-molecular-weight phenolic compound, specifically a hindered phenol antioxidant. This product matters for its role as a highly effective stabilizer that protects materials from oxidative degradation, thereby extending their service life and maintaining performance. It is needed by manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance the durability and thermal stability of their products.

Application

• Primary antioxidant in polyolefins (e.g., polyethylene, polypropylene) to prevent thermal-oxidative degradation during processing and end-use.
• Stabilizer additive in lubricating oils, greases, and synthetic fluids to inhibit oxidation and sludge formation.
• Key component in antioxidant blends and masterbatches for plastics and elastomers, offering synergistic effects with other stabilizers.
• Protective additive in adhesives, sealants, and coatings to prevent embrittlement and loss of adhesive properties.
• Stabilizing agent for hydrocarbon-based fuels and transformer oils to improve shelf life and operational stability.
• Intermediate in the synthesis of more complex, high-performance antioxidant systems for demanding applications.

Quality Control

Our 2,6-Dioctadecyl-p-cresol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, melting point, and antioxidant efficacy. Certificates of Analysis (COA) detailing results for all critical parameters are available upon request to support your quality assurance and regulatory compliance 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.
