Indupa ("Indústrias Patagonicas") was established in Río Negro Province (Argentina) on September 16, 1948, and became a leading local producer of chlorine, Polyvinyl chloride resins (PVC), and caustic soda. It relocated operations to the petrochemical center in Bahía Blanca in 1986; but an economic crisis in subsequent years forced it into government receivership in 1993. Re-privatized in 1995 to a consortium led by Dow Chemical, Indupa was acquired in 1996 by Brussels-based Solvay, which owns a 51% stake. The company, in turn, acquired Solvay do Brasil and its Santo André facility (opened in 1941) in 1998.
