Description

2.6-Dicyclohexylphenol CAS NO 4821-19-6 is a sterically hindered phenolic compound featuring two cyclohexyl substituents ortho to the hydroxyl group. This unique molecular structure makes it a valuable intermediate and performance additive, particularly as an antioxidant and stabilizer in polymer systems. It is essential for manufacturers in the plastics, rubber, and specialty chemical industries seeking to enhance product longevity and thermal stability.

Application

• Polymer Antioxidant: Acts as a primary antioxidant to inhibit thermal and oxidative degradation in polyolefins (e.g., polyethylene, polypropylene) and synthetic rubbers.
• Chemical Intermediate: Used in the synthesis of more complex hindered phenol antioxidants, phosphite stabilizers, and other specialty additives.
• Lubricant & Fuel Additive: Serves as an antioxidant additive in industrial lubricants, greases, and fuels to prevent gum formation and acid generation.
• UV Stabilizer Synergist: Works in conjunction with other stabilizers to improve the weatherability and light stability of plastic materials.
• Resin Modifier: Imparts improved processing stability and color retention to engineering plastics and thermoplastic elastomers.
• Research & Development: Employed in academic and industrial R&D for studying steric effects, reaction kinetics, and developing new stabilization systems.
