R-222
Rutile Titanium Dioxide (TiO₂) is a specific form of Titanium Dioxide, which is a widely used pigment due to its outstanding properties. Titanium dioxide occurs in nature in three main forms: rutile, anatase, and brookite. Of these, rutile is the most stable and dense form, with specific characteristics that make it particularly valuable in various applications. Here are some key aspects of rutile titanium dioxide:
High Refractive Index: Rutile titanium dioxide has one of the highest refractive indices of any known material (about 2.76), which gives it excellent light-scattering capabilities. This property makes it highly effective as a white pigment, providing opacity and brightness to products.
UV Absorption: Rutile TiO₂ is an effective UV absorber, making it an important ingredient in sunscreens and products requiring UV protection, such as plastics and coatings.
Chemical and Physical Stability: It is chemically inert and thermally stable, which makes it suitable for use in outdoor applications where resistance to weathering is important.
Applications: Rutile titanium dioxide is used in a wide range of applications, including paints and coatings, plastics, paper, inks, textiles, and food colorants. It is also used in cosmetics, especially in products like sunscreens and makeup, due to its ability to protect the skin from UV rays.
Production Methods: There are two primary methods for producing titanium dioxide: the sulfate process and the chloride process. The chloride process is generally used to produce rutile titanium dioxide, as it results in a purer and brighter pigment compared to the sulfate process.
Safety and Environmental Considerations: While titanium dioxide is considered non-toxic and safe for use in many applications, there is ongoing research and discussion regarding its safety, particularly in nanoparticle form, in terms of inhalation and environmental impact.
●Product Description
R-222 is a high-grade universal rutile titanium dioxide product produced by using sulfuric acid process and selecting high-quality raw materials.ZrO2, Al₂O₃ inorganic homogeneous coating process and adopt advanced technology to control the manufacturing process.and after a special organic surface treatment.
●Product Features
(1) It is easily wet and dispersed, and has good compatibility with other resin mixing.
(2) The color phase and brightness are relatively stable, and has excellent adhesion, weather resistance, covering, anti-powder, yellowing resistance and other multi-functional application performance.
(3) The product is common in oily and water-based system products, and its high dispersion and high covering applications are particularly significant in oily system products (paint, paint, or ink, etc.).
