| TiO2 – uses and properties Titanium dioxide (TiO2 ) pigments are white inorganic pigments used primarily in the production of paints, printing inks, paper and plastic products. TiO2 is also used in many white or coloured products including foods, cosmetics, UV skin protection products, ceramics, fibres, rubber products and more. TiO2 pigments are inert, do not react with other materials and are thermally stable, non-flammable and non toxic. Titanium dioxide has a remarkably high refractive index and an exceedingly high reflectance. It offers maximum opacity or hiding power as well as imparting whiteness and brightness to the products in which it is used. It helps paint to cover or mask other materials. It is what makes plastic packages pure white and opaque. It prevents show-through on printed paper materials, making it easy to read brochures and literature. It also affords protection from UV degradation. TiO2 manufacturing TiO2 pigments are made from one of two chemical processes - the chloride process which produces TiO2 products by reacting titanium ores with chlorine gas; and the sulphate process which produces TiO2 products by reacting titanium ores with sulphuric acid. 70% of European production (1.5 million tonnes per annum) is from the sulphate route and 30% from chloride. Chloride and sulphate pigments are both used in a wide range of applications. There are some preferred end uses for pigments from each process. TiO2 - an environmentally responsible industry In Europe, all TDMA TiO2 companies are signatories to ‘Responsible Care’. Many have achieved, or will soon achieve, ISO 14001 or EMAS, demonstrating their commitment to continuous environmental improvement. The manufacture of TiO2 by the chloride and sulphate processes is already covered by its own specific EU directive which stipulates stringent limits for liquid and gaseous emissions. Treatment processes to comply with the EU directive have been implemented in the last decade and use the best available techniques. Over the past 20 years, the European TiO2 industry has invested about € 1.4 billion in environmental improvement. |
