High Fire Retardancy Na2B4O7.5H2O, CAS 12179-04-3 Borax Pentahydrate for Flame Retardant Material
1. Borax Pentahydrate Introduction
Borax pentahydrate, also known as disodium tetraborate pentahydrate, is a crystalline form of borax composed of sodium, boron, oxygen, and water molecules. It is chemical formula is Na2B4O7.5H2O. Borax pentahydrate boron content is about 15% and boron oxide content is more than 48%. Borax Pentahydrate is commonly used in various industrial and household applications due to its unique properties. It is known for its role as a cleaning agent, as a flux in welding, as a buffering agent in chemical laboratories, and even as a component in some cosmetics and pharmaceuticals. Its ability to dissolve in water and form alkaline solutions makes it versatile for a range of uses. With its distinctive properties and wide-ranging applications, borax pentahydrate plays a significant role in numerous industries and daily activities.

3. Borax Pentahydrate for Flame Retardant Material
Borax pentahydrate change the oxidation reactions in the combustion
of cellulosic materials to cause the formation of carbon residue.
This char acts as a barrier to combustion and diverts the
decomposition products that would otherwise smolder. Borax
pentahydrate, in combination with boric acid, is particularly
effective in reducing the flammability of cellulosic materials.
Borax pentahydrate is often employed in flame retardant materials due to its ability to enhance the fire resistance of various products. Here are some key ways in which borax pentahydrate is utilized in flame retardant applications:
Synergistic Effect: Borax pentahydrate is often used in combination with other flame retardants to create a synergistic effect that enhances the overall fire resistance of materials. When used in conjunction with other flame retardant compounds, borax pentahydrate can improve the effectiveness of the flame retardant system.
Char Formation: When exposed to high temperatures, borax pentahydrate can promote
the formation of a protective char layer on the surface of
materials. This char layer acts as a barrier, insulating the
material from the heat source and slowing down the spread of
flames.
Smoke Suppression: Borax pentahydrate can help reduce the amount of smoke and toxic
gases generated during a fire. By inhibiting the release of
volatile compounds, it can contribute to a safer environment in the
event of a fire.
Thermal Stability: Borax pentahydrate enhances the thermal stability of materials,
helping them withstand high temperatures without igniting or
sustaining combustion.
