Description

2,2'-Methylenebis[6-Cyclopentyl-p-Cresol] is a high-performance, sterically hindered phenolic antioxidant. This compound matters for its exceptional efficacy in protecting polymers and other organic materials from oxidative degradation, thereby extending their service life and maintaining performance. It is primarily needed by manufacturers in the polymer, rubber, lubricant, and specialty chemical industries seeking reliable stabilization solutions.

Application

• Primary antioxidant for polyolefins (PP, PE) and engineering plastics to prevent thermal-oxidative degradation during processing and end-use.
• Stabilizer for synthetic rubbers and elastomers, including SBR, BR, and NBR, to enhance durability.
• Additive in industrial lubricants and greases to inhibit oil oxidation and sludge formation.
• Stabilizing component in adhesives, sealants, and hot-melt formulations.
• Protective agent for fuels and other hydrocarbon-based fluids.
• Intermediate for the synthesis of other specialty antioxidants and polymer additives.

Quality Control

Our 2,2'-Methylenebis[6-Cyclopentyl-p-Cresol] is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting these results is available upon request to 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). Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage of bulk quantities. Keep away from strong oxidizing agents.
