Sodium Dithionite (also known as sodium Hydrosulfite) is a white crystalline powder with a sulfurous odor. Although it is stable in dry air, it decomposes in hot water and in acid solutions.
TCP Limited is one of the leading manufacturers of pure Sodium Hydrosulphiteâ?? (popularly known as Hydros) in India. We adopt a unique process for the manufacture of Sodium Hydrosulphite, known as 'Sodium Formate Process', as against the conventional method of Zinc or Amalgam Process. The advantage of Sodium Formate Process is that the end product does not contain even traces of Zinc Iron or Mercury. Technical Assistance for the project was provided by M/s Mitsubishi Corporation of Japan, who supplied both the imported equipment and the process knowhow for the plant. Sodium Hydrosulphite" produced by the Company is being marketed throughout India through a wide network of agents & distributors. For the domestic market, we are offering a wide range of packing from 100 kgs. to 1 kg. Large size packings are available in mild steel drums and HMHDPE carboys. Images of packings are shown below
