Chemplast Sanmar Limited, the flagship company of the Sanmar Group, integration - forward and backward - is the key. The company has two main businesses! PVC and Chlorochemicals. 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. 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.
