Description

Boric Acid is a versatile and essential inorganic compound widely used across multiple industrial sectors. Its primary value lies in its role as a weak acid, a flame retardant, and a precursor to other boron compounds, offering a unique combination of chemical stability and functionality. Key industries that rely on this material include glass and ceramics manufacturing, agriculture, wood preservation, and personal care product formulation.

Application

• Glass & Ceramics Manufacturing: A critical fluxing agent to lower melting temperatures and improve the thermal and chemical resistance of borosilicate glass, fiberglass, and ceramic glazes.
• Flame Retardants: Used in cellulose insulation, textiles, and wood products to inhibit combustion and reduce flammability.
• Agriculture: Serves as a micronutrient fertilizer to correct boron deficiencies in crops and as a component in some pesticide formulations.
• Wood Preservation: Applied as a fungicide and insecticide to protect lumber and timber from decay and pest infestation.
• Personal Care & Cosmetics: Functions as a mild antiseptic, pH buffer, and preservative in eye washes, skin creams, and other topical products.
• Industrial Fluids & Metallurgy: Acts as a corrosion inhibitor in coolant systems and as a flux in metal welding and soldering processes.
• Nuclear Industry: Utilized in nuclear power plants as a neutron absorber to help control reactor fission rates.

Quality Control

Our Boric Acid is produced under strict quality management protocols to ensure batch-to-batch consistency and reliability. We offer various grades, including Technical and USP/NF, which are tested against stringent specifications for purity, heavy metals, and other critical parameters. A Certificate of Analysis (COA) is provided with each shipment to guarantee compliance with your requirements and relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking and absorption of atmospheric moisture. Separate from strong alkalis.
