Description

2,6-Bis(tert-Butyl)-5-Pentadecylphenol is a high-molecular-weight hindered phenolic compound. It serves as a highly effective antioxidant and stabilizer, protecting materials from oxidative degradation. This product is essential for manufacturers in the polymer, lubricant, and fuel industries seeking to enhance the longevity and performance stability of their formulations.

Application

• Primary antioxidant in polyolefins (e.g., polyethylene, polypropylene) to prevent thermal-oxidative degradation during processing and service life.
• Stabilizer for lubricating oils, greases, and synthetic esters to extend oil life and maintain viscosity under high-temperature operating conditions.
• Additive in fuels and biofuels to inhibit gum formation and improve storage stability.
• Stabilizing agent for elastomers and rubbers to prevent cracking and loss of elasticity.
• Intermediate in the synthesis of more complex phenolic antioxidants and specialty chemicals.
• Protective additive in adhesives, sealants, and coatings to prevent premature aging.
