Description

2,6-Bis(tert-Butyl)-4-(4-Propylcyclohexyl)Phenol is a sterically hindered phenolic compound, valued for its role as a high-performance antioxidant and stabilizer. Its molecular structure provides excellent thermal and oxidative stability, making it critical for protecting materials from degradation. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product longevity and performance under demanding conditions.

Application

• Polymer Stabilizer: Primary antioxidant for polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation during processing and service life.
• Lubricant & Fuel Additive: Antioxidant component in engine oils, industrial lubricants, greases, and fuels to inhibit sludge formation and viscosity increase.
• Adhesive & Sealant Formulations: Enhances the shelf-life and thermal stability of hot-melt adhesives, epoxy systems, and polyurethane sealants.
• Elastomer Protection: Used in SBR, NBR, and EPDM rubber compounds to prevent cracking and maintain elasticity.
• Coating Additive: Protects industrial and automotive coatings from yellowing and embrittlement caused by heat and UV exposure.
• Synergistic Blends: Often combined with secondary antioxidants (e.g., phosphites, thioesters) and light stabilizers for comprehensive stabilization packages.
• Intermediate for Specialty Chemicals: Serves as a key building block in the synthesis of more complex antioxidant molecules and polymer-bound stabilizers.

Quality Control

Our production of 2,6-Bis(tert-Butyl)-4-(4-Propylcyclohexyl)Phenol adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting results for 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 room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve efficacy. Keep away from strong oxidizing agents.
