Titanium dioxide, commonly known as titanium white, is widely recognized across various industries due to its exceptional properties. One of the key areas where it plays a significant role is in the paper industry, which ranks as the third-largest consumer of this versatile material.
In the production of low-grade paper, titanium dioxide is typically not used because of cost considerations. Instead, materials like china clay, talc, and calcium carbonate are often employed. However, these alternatives can reduce the strength of the paper and increase its weight. On the other hand, high-quality papers such as decorative paper, Bible paper, banknotes, magazine covers, and copier paper require the use of titanium dioxide. These papers benefit from the excellent whiteness, brightness, and opacity that titanium dioxide provides. It also ensures a smooth surface, prevents ink penetration during printing, and allows for thinner, lighter sheets. Compared to calcium carbonate or talc, titanium dioxide offers up to ten times better opacity and can reduce the paper’s weight by 15% to 30%.
Decorative paper, often referred to as titanium white paper, is widely used in manufacturing furniture, flooring, and wallpaper. When it comes to papers with anti-aging requirements, rutile-type titanium dioxide is preferred. High-ash papers also tend to use more rutile due to its superior hiding power. In contrast, anatase-type titanium dioxide is commonly used in low-ash papers such as Bible paper and banknotes. These types of paper require good opacity, which anatase can provide effectively.
In China, the usage of titanium dioxide in decorative paper far exceeds that in other types. This trend reflects the country's growing demand for home decoration and high-end furniture. As a result, the consumption of decorative paper has been rising steadily. However, the use of Bible paper remains limited due to its higher cost compared to regular paper. Similarly, the production and use of coin paper are regulated by the government, keeping its titanium dioxide usage stable and not significantly impacting the overall market. According to rough estimates, over 30,000 tons of titanium dioxide are used annually in decorative paper alone, with concentrations ranging between 20% to 40%. Other types of paper generally contain only 1% to 5% titanium dioxide. With many traditional paper manufacturers shifting toward producing decorative paper, the output has increased rapidly, leading to a decline in prices in recent years.
