BHT 2,6-Di-Tertiary Butyl Para-Cresol Antioxidant Lubrication Additives
Ultra-Pure Phenolic Antioxidants for Polymers & Industrial Applications
It is white crystalline particles with good antioxidant properties, which can effectively extend the induction period. When it works below 100°C, the antioxidant effect is significant.
It is widely used in petrochemical products, and can be added directly or as a mother liquor to rubber, plastic, industrial oil and fuel oil to improve the antioxidant properties of its products. It can be used together with other agents to prepare industrial gear oil, anti-wear hydraulic oil, turbine oil, transformer oil, machine tool oil and fuel oil.
Product Introduction
BHT 2,6-Di-Tertiary Butyl Para-Cresol is a premium phenolic antioxidant for polymers that delivers unmatched oxidation stability through ultra-pure (>99.9%) phenolic chemistry. This white crystalline antioxidant is specially engineered for applications requiring absolute purity and exceptional performance.
As a leading phenolic antioxidant for polymers, its sterically hindered molecular structure terminates free radical chains without introducing metallic contaminants, extending polymer life while maintaining critical material properties.
This superior phenolic antioxidant for polymers is widely used in petrochemical products, and can be added directly or as a mother liquor to rubber, plastic, industrial oil and fuel oil to significantly improve antioxidant properties. It works exceptionally well below 100°C, making it ideal for numerous polymer applications.
