Titanium Dioxide (TiO2) is an indispensable additive in the plastics industry, valued for its ability to impart whiteness, opacity, and UV stability to a vast array of plastic products. As a leading supplier of high-purity TiO2 from China, we understand the critical role this pigment plays in enhancing the aesthetic appeal and functional performance of plastics. This article outlines why TiO2 is a preferred choice for plastic manufacturers and how to source it effectively.

The Impact of TiO2 on Plastic Formulations

In plastic manufacturing, achieving a bright white color or an opaque finish often requires the addition of a white pigment. Titanium Dioxide excels in this regard due to its exceptionally high refractive index, which leads to superior hiding power and tinting strength. This allows plastic producers to create vibrant whites and effectively mask underlying colors or impurities in the polymer matrix.

Beyond aesthetics, TiO2 provides crucial UV protection. Many polymers are susceptible to degradation when exposed to ultraviolet radiation, leading to discoloration, brittleness, and loss of mechanical properties. By incorporating TiO2, manufacturers can effectively scatter and absorb UV rays, thereby protecting the plastic from photodegradation and extending its service life, especially in outdoor applications.

Choosing the Right TiO2 Grade for Plastics

  • Rutile Grade TiO2: This is the most commonly used grade in the plastics industry due to its excellent dispersibility, high opacity, and superior UV resistance. Rutile TiO2 provides the best balance of properties for most plastic applications, from packaging and consumer goods to automotive components. We recommend Rutile grade for its proven performance.
  • Anatase Grade TiO2: While less common in plastics due to its lower UV stability and tendency to chalk, Anatase may be used in specific applications where these limitations are not critical.
  • Surface-Treated TiO2: For enhanced dispersibility and compatibility with various polymer matrices, surface-treated TiO2 grades are often employed. We offer treated grades to optimize integration into your plastic formulations.
