In 1972, Grasim’s chemicals business was set up to manufacture caustic soda for the company’s VSF unit. Today, it is one of India’s largest caustic soda producers and is a market leader in the chlor-alkali segment. Over the years, Grasim’s chemicals business has created a strong foothold in the industry and offers a wide range of products from chlorine derivatives to epoxy.
Chlor-alkali
In 2016, Grasim’s merger with Aditya Birla Chemicals India Ltd. (ABCIL) helped catapult the company’s caustic soda capacity from 452 KTPA to 884 KTPA making it the largest producer of caustic soda in India back then. Today, Grasim’s total caustic soda capacity is 1,290 KTPA. Through brownfield expansion, we plan to expand the caustic soda capacity to 1,530 KTPA from 1,290 KTPA by 2024.
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 derivatives like Stable Bleaching Powder (SBP), Polyaluminium Chloride (PAC), Chlorosulphonic Acid (CSA), Chlorinated Paraffin Wax (CPW), Calcium Chloride (CaCl), Aluminium Chloride (AlCl) and Chloromethane (CMS).
Epoxy
The business’ epoxy products range from basic products like liquid epoxy resins to value added products like formulated resins, reactive diluents and hardeners. The manufacturing complex at Vilayat houses a 123 KTPA capacity epoxy plant. Through expansion, we plan to double the epoxy capacity to 246 KTPA by FY2024.
