Description

1,1-Bis(3-Cyclohexyl-4-Hydroxyphenyl)Cyclohexane is a high-purity, sterically hindered phenolic compound that serves as a highly effective antioxidant and stabilizer. Its molecular structure provides excellent thermal and oxidative stability, making it a critical additive for protecting materials from degradation. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance the longevity and performance of their formulations under demanding conditions.

Application

• Primary antioxidant and stabilizer in polyolefins (e.g., PP, PE) and engineering plastics.
• Additive in synthetic lubricants, greases, and transformer oils to prevent oxidative degradation.
• Stabilizing agent for adhesives, sealants, and elastomers to improve shelf-life and performance.
• Intermediate in the synthesis of more complex, high-performance phenolic antioxidants.
• Used in fuel additives to improve the oxidative stability of gasoline and diesel.
• Potential application as a stabilizer in food-contact compliant polymer materials (subject to specific regulatory approval and grade).

Quality Control

Our production of 1,1-Bis(3-Cyclohexyl-4-Hydroxyphenyl)Cyclohexane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry benchmarks. Certificates of Analysis (COA) documenting 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 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.
