Application
Boric Acid is a multifunctional compound used across a variety of industrial applications. In glass and glass fiber production, it acts as both a flux and a network former, aiding the melt process and enhancing final product properties by reducing melting temperatures in fiberglass. In ceramics—including frits, glazes, and enamels—it promotes glass formation, lowers viscosity and surface tension, and improves strength, durability, and scratch resistance. Boric Acid also serves as a flame retardant, effectively reducing the flammability of materials such as cellulose insulation, wood composites, and cotton batting used in mattresses. In adhesives, it is incorporated into starch formulations for corrugated paper and functions as a peptizing agent in the production of casein- and dextrin-based adhesives. Additionally, it can be combined with petroleum or vegetable oils to produce lubricants for ceramic or metal surfaces. Boric Acid is also used in manufacturing textile fiberglass for plastic reinforcement and, with its conjugate base, serves as a primary or adjunct pH buffer in swimming pool systems.
