Zinc Borate (ZB2335,ZB3.5H2O) (2ZnO·3B2O3·3.5H2O CAS NO.1332-07-6 / 138265-88-0) is produced by boric acid process with high purity, high content of ZnO and B2O3 and high thermal stability. zinc borate flame retardant is used as an environmentally-friendly additive halogen- free flame retardant and smoke suppressant in various polymer systems in engineering plastics, rubber based compounds such as hose, conveyor belt, coated canvas, FRP, wire and cable, electrical components, coating and painting, etc.
Anhydrous zinc borate (CAS No. 12767-90-7) is prepared by removing crystal water from 2ZnO·3B2O3·3.5H2O at high temperature. Compared with other zinc borate, it has higher thermal stability and can be used at higher processing temperatures .Anhydrous zinc borate is used for polymer flame retardant systems with high processing temperature requirements such as high-temperature nylon, polyester, polyetherketone, polysulfone, and fluoro polymers whose processing emperature is higher than 290°C.
From the appearance, zinc borate appears in the form of white fine powder, with uniform texture and pure color, giving people a high-quality intuitive feeling. This delicate texture is not only convenient for storage and transportation, but also easier to mix evenly with other materials in practical applications, providing convenience for subsequent processing and production.
In terms of physical properties, zinc borate has a low density, approximately between 2.67-2.78g/cm ³, which allows it to be added to various materials without significantly increasing the weight of the product, making it advantageous in applications with strict weight requirements. At the same time, it also has good thermal stability and can withstand a certain degree of high temperature without decomposition or deformation. It can usually remain stable below 300 ℃, which makes it stable in high-temperature processing technology and ensures that product quality is not affected.
In terms of chemical properties, zinc borate is a weak acid weak base salt with a certain buffering effect. It has low solubility in water, strong chemical stability, and can maintain its structural and performance stability in different chemical environments. In some specific chemical reaction systems, zinc borate can also play a catalytic role, promote the progress of the reaction, and exhibit good chemical activity and selectivity.
Zinc borate has a wide range of applications, with its leading role being in the field of flame retardancy. It is an environmentally friendly flame retardant and flame retardant enhancer with excellent performance. When used in combination with other flame retardants such as aluminum hydroxide, magnesium hydroxide, etc., it can produce a strong synergistic effect. During the combustion process of materials, zinc borate decomposes upon heating, and the resulting borides form a glassy protective film on the surface of the material. This protective film can isolate oxygen and heat, prevent the escape of flammable gases, and effectively suppress the spread of combustion. This efficient flame retardant performance has made it widely used in many materials such as plastics, rubber, fibers, coatings, etc., to safeguard people's lives and production safety. Zinc borate plays a crucial role as a flux and additive in the ceramic and glass industries. It can lower the melting temperature of ceramics and glass, promote the sintering process, and improve the mechanical strength and chemical stability of the product. At the same time, it can also improve the optical properties of glass, making it more transparent and uniform, enhancing the quality and aesthetics of glass and ceramic products. In the electronics industry, zinc borate is used as a packaging material for manufacturing electronic components. It can improve the insulation performance, thermal stability, and chemical corrosion resistance of packaging materials, ensuring stable operation of electronic components in complex environments and extending the service life of electronic devices.

Through in-depth exploration of its microstructure, cyanuric acid melamine is formed by the precise chemical synthesis reaction between melamine and cyanuric acid. This unique molecular combination endows it with a series of extremely excellent properties, making it an indispensable key element in the field of materials.
Intuitively, cyanuric acid melamine presents a crystal powder state as white as snow, with an extremely delicate texture. Each tiny particle is uniform and flawless in color, without any trace of impurities. This delicate and pure appearance not only gives people a high-quality visual experience, but also lays a solid foundation for its uniform mixing with other materials in practical applications, ensuring that it can fully exert its own efficiency in various complex material systems.
In terms of physical properties, cyanuric acid melamine can be considered outstanding. It has a high decomposition temperature, usually above 300 ℃ before gradually decomposing, which allows it to maintain high stability in high-temperature environments. In production processes such as plastic high-temperature injection molding and rubber vulcanization that require high-temperature processing, cyanuric acid melamine will not decompose or deteriorate due to high temperatures, effectively ensuring that the quality and performance of the final product are not affected. At the same time, its density is within a suitable range, which enables it to easily achieve uniform dispersion when integrated into various material systems, fully releasing its functional advantages, and avoiding precipitation or agglomeration due to density differences, providing stable and reliable support for the improvement of material performance.
In terms of chemical properties, cyanuric acid melamine exhibits excellent stability. It has a high degree of chemical inertness and is not prone to chemical reactions with common chemicals. This characteristic allows it to function safely in various complex and changing chemical environments, whether it is a strong acidic or alkaline environment or a corrosive special medium. It can always maintain its structural integrity and performance stability. More importantly, it belongs to environmentally friendly materials and does not contain any substances that are harmful to human health or cause pollution to the environment. Throughout the entire production process and product lifecycle, we strictly adhere to the concept of green environmental protection and will not produce any toxic or harmful waste, fully meeting the urgent global demand for green and sustainable materials.
Cyanuric acid melamine has a wide range of applications and plays a crucial role in the field of flame retardancy. As an excellent nitrogen based environmentally friendly flame retardant, when added to polymer materials such as plastics, rubber, and fibers, it can significantly and efficiently enhance the flame retardant properties of the materials. Once encountering a fire hazard, cyanuric acid melamine decomposes rapidly upon heating, releasing inert gases that can effectively dilute the concentration of oxygen and flammable gases in the surrounding environment. At the same time, it cuts off the chain reaction path that the combustion reaction relies on to continue, thereby quickly and effectively preventing the spread of flames, and buying valuable time for personnel safety evacuation and firefighting rescue operations. In the manufacturing of electronic and electrical enclosures, its application greatly improves the fire resistance of products and effectively reduces the risk of fires caused by electrical faults; In the production of insulation layers for wires and cables, it coats the cables with a reliable layer of fire-resistant "armor" to ensure the safety of power transmission; Adding cyanuric acid melamine to car interior materials provides an important guarantee for the safety of drivers and passengers during driving. In addition, in the coatings industry, it is widely used as a key flame retardant additive in building coatings, industrial protective coatings, and other fields, building strong fire barriers for buildings and industrial facilities, greatly improving their protection ability in fires.
