Sodium Tetraborate Decahydrate is more popularly known as Borax10 mol. It is often used as a buffering agent. Borax decahydrate is utilized as a cleaning agent, especially for laundry purposes. Researchers may employ borax for surface treatment purposes, such as cleaning, etching, or modifying the surface properties of materials. Borax decahydrate serves as a preservative and pH buffer. It helps extend the shelf life of certain products and maintains their desired pH levels. Borax 10 mol is the least concentrated sodium borate product, because it has the most bound water (10 molecules). It is found in detergents, and personal care products. It is used to make glass, ceramics, and insulation. It is a flux in metal recovery, wire drawing and refractories. It is also a corrosion inhibitor in automotive antifreeze, and a preservative in casein-based adhesives.

Turkey Brand ETiMADEN Borax Pentahydrate
1. Granular borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate. Borax is a component of many detergents, cosmetics, and enamel glazes. It is used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound, in the manufacture of fiberglass, as a flux in metallurgy, neutron-capture shields for radioactive sources, a texturing agent in cooking, as a cross-linking agent in slime, as an alkali in photographic developers, as a precursor for other boron compounds, and along with its inverse, boric acid, is useful as an insecticide.
2. Borax pentahydrate is generally written as Na2B4O7�?�¢?�?�¢5H2O. Powdered borax is white, consisting of soft colorless crystals that dissolve in water.
3. Usually a white powder contains colorless, odorless and salty crystals. The specific gravity is 1.73. All crystal water is
lost at 350-400C. Soluble in water and glycerol, slightly soluble in alcohol. The aqueous solution is strongly alkaline.
4. For borax pentahydrate we import it from Turkey and American. Their brand name is ETiMADEN and THREE ELEPHANT.

We are a leading supplier of electroplating chemicals, industrial polishing and welding consumables, water treatment, powder coating, fertilizers. We stock and carry an extensive range of ready to use chemicals.

Sodium Thiosulfate is a white translucent crystals or powder that is common as the pentahydrate form; melting at 48 C; readily soluble in water and oil of turpentine; aqueous solution is slightly alkaline which decompose to sulfate and sulfide in the air. It is a moderate reducing agent. It is a source of thiosulfate ion (S2O3-2) (dissolves silver salts). Its major use is as a fixing agent in photography for developing film and the extracting silver from ore. It is used in chrome-tanning leather and in chemical manufacture as a source of sulfide ion. It is also used in paper, textile and gas purification.

Sodium metasilicate pentahydrate enhances the suspension of removed soils such as grease and dirt deposits and prevents reaccumulation. For this reason, it's commonly used in manufacturing high-efficiency in soaps, detergents, and metal cleaners. It is extensively used in the manufacturing of Detergents, Silica Gel, Card-board, Paper, Textiles, Paints, Adhesives, Pottery, Sanitary-ware, Refractories, Foundry and Wood Processing Industries because of it's very good binding, adhesive, bleaching and sizing properties respectively.

Key Properties:

Sodium Sesquicarbonate (Borax Substitute) is a unique alkaline product that is ideal for a wide range of household, personal care and industrial uses.
Manufactured by Tata Chemicals Europe at its dedicated plant in the UK, Sodium Sesquicarbonate (Borax Substitute)is a free-flwing, non-irritant white powder.
It is produced by the recrystallisation of Sodium Carbonate and Sodium Bicarbonate, to form a single crystal of Sodium Sesquicarbonate (Borax Substitute)Na2CO3.NaHCO3.2H2O.
Sodium Sesquicarbonate (Borax Substitute)avoids pH surges seen with blends of Sodium Bicarbonate and Sodium Carbonate due to their different dissolution rates.
The varied and valuable properties of Sodium Sesquicarbonate (Borax Substitute), such as water softening, high solubility, mild alkalinity, free flow and excellent buffering capacity, lead to uses in a wide range of applications.
