The Company entered into the Chemicals business to manufacture Caustic Soda, an input for VSF. The business has grown multi-fold and today Grasim is the largest caustic soda producer in India. It also produces a range of chlorine derivative products and epoxy.

At Vilayat complex, Grasim has setup a 1,23,097 MTPA capacity plant of Epoxy. The business offers entire range of epoxy products to customers from basic products like liquid epoxy resins to value added products like formulated resins, reactive diluents and hardeners. Epoxy has wide range of applications including civil coatings, composites (Wind Energy Blades), adhesives, paint, electrical and electronic industry and can coating.

With the merger of Aditya Birla Chemicals India Ltd. (ABCIL) in FY 2016 and after debottlenecking, the caustic soda capacity has increased from 452K TPA to 840K TPA. The merger has enabled the geographical diversification for Grasim across the country, besides bringing in operational and financial synergies.

Key Facts


The business uses cost-effective membrane cell technology and is largely self-sufficient in power. For gainful utilisation of chlorine, the business has portfolio of Chlorine Derivative like Stable Bleaching Powder (SBP), Polyaluminium Chloride (PAC), Chlorosulphonic Acid (CSA), Chlorinated Paraffin Wax (CPW), Calcium Chloride (CaCl) and Aluminium Chloride (AlCl), with a total capacity of 243K tonnes.

Chlorine Derivatives:

Anhydrous aluminium chloride
Anhydrous aluminium chloride is the principal catalyst used in the Friedel-Crafts reaction, both acylations and alkylations. The product also finds application in the manufacture of Ibuprofen and other bulk drugs, ethyl benzene, isopropyl benzene, titanium dioxide, hydrocarbon resins, terpene resins and polybutenes.

The Friedel-Crafts reactions are used, for example, in the preparation of anthraquinone for the dyestuffs industry (phthalo-cyanine blues and greens) from benzene and phosgene.

Chlorinated paraffin formulations
Chlorinated paraffin formulations are used in a wide range of industrial applications including flame retardants and plasticisers. The product functions as an additive in metal working fluids, sealants, paints and coatings.
The manufacturing processes include strict quality control measures and are certified under ISO:9001, OHSAS:18001 and SA:8000 by BSI.

Chloro sulphonic acid
Chlorosulphonic acid is primarily used to produce sulphates, sulphonates, sulphonyl chlorides with organic compounds like hydrocarbons, alcohols, phenols, amines.

Polyaluminium chloride (PAC)
Polyaluminium chloride (PAC) is manufactured in both liquid and powder form. The product is used in deodorants and antiperspirants, as a flocculant in water purification, in treatment of drinking / potable water, wastewater treatment and paper sizing.

Stable bleaching powder
Stable bleaching powder is marketed under three brand names – Vikram, Shaktiman and Lion. It is used as a disinfectant in water treatment and also in the textiles, pulp and paper, and carpet industries.

Calcium chloride
Calcium chloride is used extensively in oil industry, for treating roads in winter and in cement paint manufacturing.
We manufacture high and consistent quality calcium chloride granules with minimum 94 per cent purity. The granular form helps customer by reducing handling trouble.
