Neobor is the most common form of sodium borate used in industry. Consisting of white crystalline granules or powder it is mildly alkaline in solution.
     The advantages of Neobor compared with borax lie in the lie in the lower transportation, handling and storage costs of a more concentrated product. Neobor is stable under ordinary conditions, free-flowing, and easily handled by air or mechanical conveying.

Main Applications
 
■     Glasses and fiber glass
        Neobor serves as a source of boric oxide (B2O3) in many compositions, including insulation fiber glass, textile fiber glass and borosilicate glasses (heat resistant illumination, cookware, medical/cosmetic containers, hollow/solid microspheres, optical lenses and sealing glass). It also provides a source of sodium, and is used in combination with boric acid where it is necessary to control the sodium to boron ratio in the glass.
The function of B2O3 in glass making is that of both flux and network former. It controls the melt and influences the final product properties.
In fiber glass, B2O3 assists “fiber zing” and gives durability in use.In borosilicate glasses, it give a low coefficient of thermal expansion (thus providing resistance to heat and thermal shock), and improves chemical durability.
 
■     Glazes and enamels
       Neobor increases the strength, scratch resistance, and chemical resistance of ceramic wares such as wall and floor tiles, tableware and porcelain, and of enameled appliances.
By controlling the coefficient of expansion, B2O3 facilitates thermal fit between glaze and body; it also reduces melting temperatures, inhibits diversification and provides for a smooth, even finish.
 
■     Some Other Applications
      Detergents and bleach, Cleaning products, Flame retardancy, Corrosion inhibition, Adhesives, Stabilizer, Emulsifier and so on.
