[Link to Product Documents] VCM We use about 85% of our VCM production in the manufacture of our vinyl resins. VCM production not used internally is sold to other vinyl resins producers in domestic and international markets. Chlor-alkali Products Substantially all of the chlorine we produce is used internally in the production of VCM. As a co-product, caustic soda further diversifies our revenue base. We sell all of our caustic soda domestically and overseas to customers in numerous industries, with the pulp and paper and chemical industries constituting our largest markets. Our other markets for caustic soda include the alumina, soap and detergent, textile and water treatment industries. ©2010 Georgia Gulf Corporation.
