Product Usage

Sodium Tetraborate Pentahydrate, also known as Borax Pentahydrate, is a highly efficient and versatile borate widely used in modern industry due to its excellent chemical stability and solubility. In the glass and ceramics industry, it is a key raw material for manufacturing heat-resistant glass, fiberglass, and glazes, significantly reducing melting temperatures while enhancing impact resistance and chemical durability. In the detergent sector, it possesses superior stain removal, pH buffering, and water-softening capabilities, making it a common ingredient in high-performance laundry liquids and multi-purpose cleaners. Additionally, it serves as a micronutrient fertilizer in agriculture to prevent boron deficiency in crops and acts as a flux in metallurgy, while playing a vital role in wood preservation and flame retardant materials.
