Description

4,4',4''-(1-Methylpropan-1-Yl-3-Ylidene)Tris(2-Cyclohexyl-5-Methylphenol) is a high-performance, sterically hindered phenolic antioxidant. This compound is valued for its exceptional ability to inhibit oxidative degradation and extend the service life of sensitive materials. It is primarily utilized by formulators and manufacturers in the polymer, lubricant, and specialty chemical industries seeking advanced stabilization solutions.

Application

• Primary antioxidant in polyolefins (e.g., PP, PE) and engineering plastics to prevent thermal-oxidative degradation during processing and end-use.
• Stabilizer additive in synthetic lubricants, greases, and transformer oils to enhance oxidative stability and prolong fluid life.
• Key component in adhesive and sealant formulations to prevent gelation and maintain viscosity stability.
• Protective agent in elastomers and rubber compounds to resist cracking and hardening caused by heat and oxygen exposure.
• Stabilizer for hydrocarbon-based fuels and industrial fluids to prevent gum and sediment formation.
• Intermediate for the synthesis of more complex, high-molecular-weight antioxidant systems.

Quality Control

Our production of 4,4',4''-(1-Methylpropan-1-Yl-3-Ylidene)Tris(2-Cyclohexyl-5-Methylphenol) adheres to a strict quality management system. Every batch is analyzed to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, melting point, and impurity profiles is provided with each shipment to guarantee consistency and 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, maintaining an inert atmosphere (e.g., under nitrogen) in the container headspace is recommended to preserve efficacy. Keep away from strong oxidizing agents.
