R-221
Rutile Titanium Dioxide (TiO₂) pigment is a highly valued material used extensively across various industries for its exceptional properties. Rutile is one of the three naturally occurring crystal forms of Titanium Dioxide, the others being anatase and brookite. Rutile TiO₂ is particularly favored for its higher refractive index and greater stability compared to the other forms. Here are some key aspects of rutile TiO₂ pigment:
High Refractive Index: Rutile TiO₂ has one of the highest refractive indices of any material, making it an excellent light-scattering agent. This property is crucial for its use as a white pigment, providing high opacity and brightness.
UV Absorption: It effectively absorbs ultraviolet light, which makes it useful in products requiring UV protection, such as sunscreens, plastics, and coatings.
Stability and Durability: Rutile TiO₂ is chemically stable and resistant to heat and light, making it ideal for outdoor applications where durability is important.
Wide Range of Applications: Its use spans across various industries, including paints and coatings, plastics, paper, inks, and even in food colorants and cosmetics.
Manufacturing Processes: Rutile TiO₂ is typically produced through either the sulfate process or the chloride process, with the latter generally resulting in a purer form of the pigment.
Safety Considerations: While generally considered safe, there is ongoing research into the potential health and environmental impacts of TiO₂, especially in its nanoparticle form.
Due to its superior qualities, rutile TiO₂ pigment is integral in enhancing the performance, appearance, and longevity of a wide array of products.
