Titanium dioxide (TiO2) has several major uses across various industries. Some of the significant applications of titanium dioxide include:
- Paints and Coatings: Titanium dioxide is the most widely used pigment in the paint and coatings industry. It provides opacity, brightness, and excellent hiding power, improving the coverage and color intensity of paints. It is used in both interior and exterior paints, as well as in industrial coatings.
- Plastics and Polymers: Titanium dioxide is incorporated into plastics and polymers to enhance their whiteness, brightness, and opacity. It helps achieve a consistent color and appearance in plastic products such as packaging materials, PVC pipes, automotive components, and consumer goods.
- Cosmetics and Skincare Products: Titanium dioxide is a common ingredient in cosmetics, skincare products, and sunscreens. It acts as a physical UV filter, reflecting and scattering UV rays to protect the skin from sun damage. It provides broad-spectrum protection against both UVA and UVB rays.
- Food and Beverage Industry: Titanium dioxide is used as a food coloring agent (E171) to provide a bright white color to various food products. It is commonly found in confectionery, bakery goods, dairy products, sauces, and beverages. However, its use in food has raised concerns in some regions due to potential health risks, and regulations may vary.
- Paper and Printing: Titanium dioxide is employed in the paper industry to enhance the opacity, brightness, and printability of paper products. It improves the whiteness and reduces show-through, resulting in high-quality prints and better overall appearance.
- Catalysis and Chemical Reactions: Titanium dioxide is utilized as a catalyst in several chemical reactions, particularly in the field of photocatalysis. It can accelerate reactions when exposed to light, making it valuable for environmental applications such as air and water purification, self-cleaning surfaces, and reducing pollutants.
- Ceramics and Glass: Titanium dioxide is added to ceramics and glass to improve their durability, opacity, and brightness. It contributes to the white color of ceramic glazes and enhances the optical properties of glass, making it suitable for various applications like tableware, tiles, and architectural glass.
