In the realm of industrial chemicals, few compounds offer the multifaceted benefits of Zinc Borate, particularly when it comes to enhancing fire safety. With its CAS number 10361-94-1, this inorganic additive has become indispensable across various sectors. As a prominent manufacturer and supplier, we are dedicated to providing comprehensive insights into Zinc Borate, from its core properties to its diverse applications, and guiding procurement managers and research scientists on effective sourcing strategies.

At its core, Zinc Borate is a white crystalline powder known for its remarkable fire retardant and smoke suppressant capabilities. Its chemical formula often includes hydration, with common forms like 2ZnO·3B2O3·3.5H2O. The key to its effectiveness lies in its thermal decomposition. Upon exposure to heat exceeding approximately 290°C, Zinc Borate releases water of hydration. This process is endothermic, meaning it absorbs heat energy from the surrounding environment, thus cooling the material and hindering combustion. Crucially, the released water vapor dilutes flammable gases and slows down the burning rate.

Beyond cooling, Zinc Borate excels at promoting char formation. As it decomposes, it can facilitate the creation of a stable, glassy char layer on the surface of a material. This char acts as a physical barrier, insulating the underlying substrate from heat and oxygen, thereby preventing the progression of flames. This combined cooling and barrier effect makes Zinc Borate a highly efficient fire retardant. Furthermore, it significantly suppresses the generation of smoke, a critical factor in improving safety and escape routes during fire incidents.

The applications of Zinc Borate are extensive, largely driven by its effectiveness and its status as a halogen-free, environmentally friendly additive. In the plastics industry, it is a vital component for enhancing the flame retardancy of polymers such as PVC, polyolefins, polyamides, and epoxy resins. For rubber manufacturers, it contributes to the production of fire-resistant elastomers. The textile industry utilizes Zinc Borate for treating fabrics, carpets, and upholstery to meet stringent fire safety standards. Moreover, it finds application in coatings, adhesives, and pigments, contributing to the fire performance of these products.

A significant advantage of Zinc Borate is its synergistic effect with other flame retardant additives. It works exceptionally well in conjunction with antimony trioxide, alumina trihydrate (ATH), magnesium hydroxide, and various halogenated compounds. This synergy allows formulators to achieve enhanced fire retardancy with potentially lower overall additive loadings, leading to cost savings and optimized material properties. Understanding these synergistic relationships is key for product developers seeking the most effective and economical solutions.
