Description

Magnesium Borate is an inorganic compound valued for its unique thermal and chemical stability, making it a versatile functional additive. Its primary commercial significance lies in its role as a flame retardant and smoke suppressant in polymer composites and coatings. This material is essential for manufacturers in the plastics, ceramics, and specialty chemical industries seeking to enhance the fire safety and thermal properties of their products.

Application

• Flame Retardant & Smoke Suppressant: A key additive in PVC, polyolefins, rubber, and epoxy resins to improve fire resistance and reduce smoke emission.
• Ceramic & Glass Production: Used as a fluxing agent and to modify thermal expansion properties in specialty glasses and ceramic glazes.
• Lubricant Additive: Serves as a solid lubricant and anti-wear agent in high-temperature greases and coatings.
• Corrosion Inhibitor: Incorporated into protective paints and coatings for metals, particularly in high-temperature environments.
• Catalyst & Catalyst Support: Employed in certain organic synthesis reactions and as a support material for other catalysts.
• Wood Treatment: Acts as a component in fire-retardant treatments for wood and cellulose-based materials.
