Description

Disodium Octaborate Tetrahydrate is an inorganic boron compound with significant industrial utility. This versatile chemical serves as a highly effective source of boron, a critical element in numerous manufacturing and agricultural processes. It is essential for industries requiring reliable flame retardancy, wood preservation, and micronutrient supplementation, offering a stable and soluble form of boron for consistent performance.

Application

• Flame Retardant: A key component in cellulose insulation, plastics, textiles, and coatings to inhibit combustion and meet fire safety standards.
• Wood Preservative: Used in pressure-treated lumber and composite wood products to protect against fungal decay and insect damage.
• Agricultural Micronutrient: Provides essential boron for soil amendment and foliar fertilizers to correct deficiencies and promote healthy plant growth.
• Glass & Ceramics Manufacturing: Acts as a fluxing agent to lower melting temperatures and improve the thermal and chemical durability of borosilicate glasses and ceramic glazes.
• Adhesives & Sealants: Imparts fire-retardant properties and can act as a cross-linking agent in specific formulations.
• Metal Treatment: Employed in certain metalworking fluids and as a component in formulations for corrosion inhibition.
