Birla Sodium Sulphate is an ideal filler and volume builder, as it is free flowing, bright, soluble and white.
Source of sodium and acts as a refining agent and prevents formation of scum during the melting of sand.
In the Kraft process, Birla Sodium Sulphate is used in the cooking liquor recovery circuit to replenish the lost sodium and sulphur.
Birla Sodium sulphate aids in producing a more “level” colour and better distribution of the dye on the fiber with deeper shades.
Free flowness, low chloride content and suitable pH are the USPs of the Birla Sodium Sulphate for dye manufacturing. It is also used to produce potassium sulphate, aluminiumsulphate, etc.
Birla Sodium Sulphate is used as an agent, facilitating removal of iron and other impurities from molten zinc metal.
