Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Methyl-.Omega.-Hydroxy-, Ester With Boric Acid (H3Bo3) is a specialized organoboron compound derived from the esterification of a methoxy-terminated polyethylene glycol (PEG) derivative with boric acid. This chemical is valued for its unique combination of polymeric properties and boron's functionality, making it a versatile intermediate and performance additive. It is primarily utilized in advanced material science, polymer modification, and as a component in specialty lubricants and heat transfer fluids where thermal stability and controlled reactivity are required.

Application

• Polymer Additive & Modifier: Acts as a cross-linking agent, plasticizer, or stabilizer in specialty polymer formulations to enhance thermal and mechanical properties.
• Lubricant & Grease Component: Used in the formulation of high-performance synthetic lubricants and greases, contributing to extreme pressure (EP) and anti-wear characteristics.
• Heat Transfer Fluid Additive: Serves as a stabilizing or performance-enhancing additive in glycol-based heat transfer and coolant fluids.
• Chemical Intermediate: A key precursor in the synthesis of more complex boron-containing compounds for research and industrial applications.
• Adhesive & Sealant Formulations: Imparts moisture resistance and improves adhesion properties in specific adhesive and sealant systems.
• Textile & Fiber Treatment: Used as a processing aid or finishing agent to impart flame retardancy or other functional properties to textiles.
