caustic soda processing facilities

One of Tokuyama's main products is caustic soda, for which its annual production capacity is 490,000 metric tons, the third largest in Japan. Caustic soda is used in an array of industrial settings. For example, in the papermaking industry it is used to dissolve pulp, while in the mining industry it is used to refine alumina, a raw material in aluminum. Chlorine is produced together with caustic soda, and this business utilizes it to make a diversity of products, including propylene oxide, which is a feedstock for urethane, as well as raw materials for polyvinyl chloride and chloromethane for chlorinated solvents. This product diversity is a hallmark of Tokuyama, and also helps lower the impact of demand fluctuations in specialized markets on these diverse products.
This business also produces vinyl chloride monomer, a feedstock for polyvinyl chloride manufactured and sold by Tokuyama Group subsidiary, Shin Dai-ichi Vinyl Corporation. Polyvinyl chloride can be processed in many different ways to modify the shape, making it a useful material for electrical wire coverings, film sheets, pipes for water and sewage systems, building materials, and other items found in daily life. The polyvinyl chloride is made with about 60% chlorine and 40% petroleum, an exceptionally low amount of petroleum for a plastic. As such, this product helps save resources and reduce dependence on oil.
