At Chemplast Sanmar Limited, the flagship company of the Sanmar Group, integration - forward and backward - is the key. The company’s main businesses are – PVC, Chlorochemicals and Piping Systems. The synthesis that underlies the polymer chemistry of PVC manufacture is also reflective of the company’s approach to business. The basic feedstock for its PVC plant, ethylene and chlorine, come from its industrial alcohol plant at Panruti and its own chloralkali facilities at Mettur and Karaikal. In pursuit of its forward integration strategy, the company has re-entered the PVC pipes business. The manufacturing facilities located at Ponneri near Chennai has a capacity of around 25,000 tonnes per annum of a wide variety of pipes such as pressure pipes, casing and screen pipes, SWR pipes, plumbing pipes and conduits. The piping systems are well-known in the market for high quality under the brand name “Trubore”. The Chlorochemicals Division of Chemplast, itself the result of backward integration by the group, manufactures a wide range of products using a highly integrated manufacturing process. These downstream products are either chlorine derivatives or chlorine users in the production process. The salt needed for chlorine manufacture is supplied by Chemplast’s own salt fields at Vedaranyam. The electrolysis process of manufacturing chlorine, is power-intensive, but Chemplast is fully equipped to generate sufficient captive power to meet its entire requirements. All this makes Chemplast one of the most integrated chemical plants in the country with a closed manufacturing loop.
Chemplast's product range falls into six distinct groups — PVC Resins, Caustic Soda/ Chlorine, Chlorinated Solvents, Refrigerant Gases, Silicon Wafers and Trubore Piping Systems. The manufacturing facilities are located at Mettur, Panruti and Ponneri in Tamil Nadu and Karaikal in the Union Territory of Pondicherry.
