Description

2-Benzyl-4,6-Bis(tert-Butyl)Phenol is a sterically hindered phenolic compound widely recognized for its antioxidant properties. This chemical serves as a highly effective stabilizer and intermediate, protecting materials from oxidative degradation and extending their functional lifespan. It is essential for manufacturers in the polymer, rubber, lubricant, and specialty chemical industries seeking to enhance product durability and performance.

Application

• Polymer Stabilizer: A primary antioxidant used in polyolefins (e.g., polyethylene, polypropylene) and other polymers to prevent thermal and oxidative degradation during processing and end-use.
• Rubber Antioxidant: Imparts aging resistance to synthetic and natural rubber products, including tires, seals, and gaskets.
• Lubricant & Fuel Additive: Functions as an antioxidant in industrial lubricants, greases, and fuels to inhibit sludge formation and viscosity increase.
• Chemical Intermediate: Used in the synthesis of more complex hindered phenol antioxidants and other specialty chemicals.
• Adhesive & Sealant Formulations: Enhances the shelf-life and stability of adhesive and sealant products by preventing resin gelling and skin formation.
• Coating Additive: Protects coatings and paints from yellowing and embrittlement caused by exposure to heat and oxygen.

Quality Control

Our production of 2-Benzyl-4,6-Bis(tert-Butyl)Phenol adheres to stringent quality management protocols. Every batch is analyzed to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee consistent quality and traceability for your formulations.

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.
