Description

2,4-Dimethyl-6-Isooctylphenol is a hindered phenolic compound valued for its antioxidant properties. It serves as a critical intermediate and stabilizer in the production of high-performance polymers and specialty chemicals. This product is essential for manufacturers in the polymer, lubricant, and fuel additive industries seeking to enhance product longevity and prevent oxidative degradation.

Application

• Polymer Stabilizer: Acts as an antioxidant and processing stabilizer in polyolefins (e.g., polyethylene, polypropylene) and other polymers to prevent thermal and oxidative degradation during manufacturing and service life.
• Lubricant & Fuel Additive: Used as an antioxidant additive in engine oils, industrial lubricants, and fuels to inhibit oxidation, reduce sludge formation, and extend operational life.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex phenolic antioxidants, UV stabilizers, and other specialty chemicals.
• Rubber Industry: Employed as an antioxidant in the production of synthetic rubbers and elastomers to protect against aging and maintain elasticity.
• Adhesives & Sealants: Incorporated into formulations to improve the thermal-oxidative stability of adhesive resins and sealant materials.

Quality Control

Our 2,4-Dimethyl-6-Isooctylphenol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, color, and moisture content 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 room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve efficacy. Keep away from strong oxidizing agents.
