Description

Lubrizol 859 is a specialized chemical additive designed to deliver high-performance characteristics in demanding industrial formulations. Its primary value lies in enhancing the stability and functional lifespan of products where oxidative degradation is a critical concern. This makes it an essential component for manufacturers in sectors such as lubricants, polymers, and functional fluids who require reliable additive technology to protect their formulations.

Application

• As an antioxidant and stabilizer in synthetic and semi-synthetic lubricants and greases.
• To improve the thermal-oxidative stability of engineering plastics and polymer compounds.
• As a protective additive in industrial hydraulic and transmission fluids to extend service life.
• Used in fuel and oil additives to prevent sludge formation and deposit control.
• Incorporated into metalworking fluids to enhance stability and reduce rancidity.
• As a performance additive in select elastomer and rubber applications.

Quality Control

Every batch of Lubrizol 859 is produced and tested under a rigorous quality management system to ensure consistent performance and purity. While specific grade specifications may vary, our standard quality assurance includes testing for key parameters such as active content and oxidative stability. A Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to guarantee compliance with your technical requirements.

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 easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening to maintain maximum efficacy. Keep away from strong oxidizing agents.
