Chemplast Sanmar – fifty years old and the flagship company of The Sanmar Group – is a major manufacturer of PVC resins, Caustic Soda, Chlorochemicals, Refrigerant gas and Industrial Salt. The manufacturing facilities are located at Mettur, Cuddalore, Panruti and Vedaranyam in Tamil Nadu and Karaikal in the Union Territory of Puducherry.

The commissioning, in September 2009, of a PVC project at Cuddalore, Tamil Nadu, was a major step forward for the Group. The facility, with an annual capacity of 3,00,000 tons, is the largest chemical project to come up in the state of Tamil Nadu for well over a decade. Chemplast Sanmar’s aggregate capacity of 3,66,000 tons makes it one of the largest PVC players in India.

The Chlorochemicals division of Chemplast, a result of backward integration by the Group, manufactures a wide range of products using a highly integrated manufacturing process.
