Description

2,6-Diisopropyl-m-Cresol is a sterically hindered phenolic compound that serves as a highly effective antioxidant and stabilizer. Its molecular structure provides excellent protection against oxidative degradation in various organic matrices. This product is essential for manufacturers in the polymer, fuel, and specialty chemical industries seeking to enhance the shelf-life and performance stability of their formulations.

Application

• Polymer Stabilizer: Acts as a primary antioxidant in polyolefins (PP, PE), elastomers, and adhesives to prevent thermal and oxidative degradation during processing and end-use.
• Fuel & Lubricant Additive: Inhibits gum formation and oxidation in gasoline, jet fuels, and industrial lubricants, improving their storage stability and performance.
• Chemical Intermediate: Used in the synthesis of more complex hindered phenol antioxidants and other specialty chemicals.
• Rubber Industry: Protects synthetic rubbers like SBR and NBR from aging and maintains their physical properties.
• Plasticizer Stabilizer: Prevents the discoloration and degradation of plasticizers such as phthalates, ensuring the longevity of flexible PVC products.
• Industrial Greases: Incorporated into grease formulations to provide oxidative stability under high-temperature operating conditions.

Quality Control

Our 2,6-Diisopropyl-m-Cresol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets the high-purity standards required for industrial applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain efficacy. Keep away from strong oxidizing agents.
