Titanium dioxide
The titanium dioxide production volume of ISK is the largest of any company in Japan (as of April 2024, according to the results of an ISK survey). In addition, ISK is the only company in Japan to produce titanium dioxide with a chloride process that is friendlier to the environment.
As our living environment becomes more colorful as living standards rise, the demand for high-quality titanium dioxide that can meet various application requirements are increasing more and more. ISK is ready to supply a wide variety of titanium dioxide products to fulfill these requirements. Under the trade name TIPAQUETM™ ISK's titanium dioxide products are well known among our customers.
