Soda Ash and Calcium Chloride Business

Recognized as a foundation business, soda ash is a basic industrial chemical that is used in a wide range of fields as a material for making glass as well as such inorganic chemicals as detergents, and also as a food and beverage additive. The Company provides this product in varying degrees of light and dense ash.

Manufactured jointly with soda ash, calcium chloride generates heat in reaction to water and lowers the freezing temperature of water, and is used as an immediate-acting antifreeze agent as well as a snow and ice remover. Subject to stringent quality control manufacturing standards, calcium chloride is also used as a food and beverage additive.

Sodium silicate cullet is a hard glass-like substance. Sodium silicate dissolved into water (water glass) is widely used in civil engineering applications including the hardening of soil and prevention of water leakages. Moreover, Sodium silicate cullet is used across a variety of fields as a raw material for products in the chemical industry including precipitated silica (white carbon) and silica gel.

Produced by reacting high-quality caustic soda in carbon dioxide, sodium bicarbonate is used in a wide range of applications from medical products (pharmaceutical use) to daily goods (food and beverage additive).

Distinguished as a crystalline with a layered structure, Purifeed is an excellent supplement of multi-charged ions in soft water. Less likely to trigger consolidation, Purifeed also prevents the formation of scale and is used as a cleaning aid (detergent builder) for clothing and dishwashing machines.

Chlor-Alkali and Vinyl Chloride Business

Produced through the electrolysis of a salt solution, caustic soda is one of Tokuyama’s hallmark products. Available in both liquid and solid form, it is widely used in the manufacture of inorganic chemical, paper, aluminum and other products. The Company’s caustic soda can also be applied to various environmental preservation processes including wastewater treatment, desulfurization, and de-acidification.

Propylene oxide is a colorless, volatile liquid and a highly flammable substance. It is mainly used as a basic feedstock for polypropylene glycol (PPG), a material used in polyurethane, and propylene glycol.

Methylene chloride is highly volatile and nonflammable, and among chlorinated solvents, it demonstrates excellent solubility for fats and oils. Consequently, methylene chloride is used in a broad array of applications as a paint remover, urethane foaming agent, and also as a reaction agent for producing polycarbonate resin. Leveraging its excellent solubility for fats and oils, methylene chloride is moreover widely used for degreasing metals.

Vinyl chloride monomers are a feedstock for polyvinyl chloride (PVC) resin. This product is largely sold to Shin Dai-Ichi Vinyl Corporation, a Tokuyama Group company that produces and sells PVC.

Polyvinyl chloride (PVC) resin has a wide range of applications and is used across a broad array of fields in both consumers' use and industrial use. Used as a feedstock for the production of PVC resin, roughly 60% of vinyl chloride resin is derived from salt, making it an environmentally friendly material.

Produced using a proprietary liquid phase chloromethane method, chloroform is used as a raw material for fluoro-resins and an extraction agent for pharmaceutical products and agricultural chemicals.

New Organic Chemicals Business

Produced using a proprietary direct hydration technique, isopropyl alcohol, which can be blended with both water and oil, is widely used in paint and ink solvents and as a compound substance for medical and agricultural chemicals.
