Fumed Silica Business

Tokuyama sells fumed silica, the main product of this business, under the brand name of REOLOSIL. Fumed Silica comes in a light, fluffy white powder. Owing to its excellent powdery texture, it is used in many common applications, such as strengthening resins, thickening paint to prevent dripping, polishing semiconductor wafers, providing an additive in pharmaceutical products, preventing ink bleeding on paper, and improving the flow and transferability of printer ink.
In its Fumed Silica Business, Tokuyama works to provide services to customers that always meet their needs while also aiming to take their technical and developmental capabilities a step further. The business offers various grades for customers to select according to their intended usages and applications. REOLOSIL falls under the general categories of hydrophilic and hydrophobic substances. For the hydrophobic version of the product, the hydrophilic surface of the particles has been hydrophobized using processing agents.
The Fumed Silica Business applied Tokuyama's proprietary technologies to develop REOLOSIL, which is made by hydrolyzing highly purified source gases at high-temperatures in hydrogen-oxygen flames. It manufactures REOLOSIL under integrated management in a closed system spanning from the implementation of initial chemical reactions to the packaging of the product. This ensures that Tokuyama's fumed silica is of high purity, has excellent dispersability, and a high-specific surface area, making it possible to be used in various kinds of applications.
The Fumed Silica Business has factories not only in Japan but also in China, and is planning to optimize its operations while ensuring a stable and continuous supply of products with the aim to expand business in global markets.
