What is Titanium Dioxide exactly?

Titanium dioxide is an important organic chemical pigment. Its main component is titanium dioxide. Two process methods are used to make titanium dioxide. One is the sulfuric acid process and one is the chlorination process. It’s used extensively in coatings.

The performance of engineering plastics depends on many factors.

The defects in titanium dioxide, as well as the strong polarity of the surface, make titanium dioxide easy to absorb water. It is also easy to agglomerate and agglomerate during storage, production, and transport. This limits its use in organic polymers. The key to wide-ranging use of titanium dioxide is surface modification to increase its dispersibility and compatibility in organic polymers. It is necessary to perform organic modification in order to improve the wetting, dispersion, and rheological characteristics of titanium dioxide in different dispersion media.


1. The Lab value of titanium dioxide powder is not affected by the use of polysiloxane, polysiloxane, or polyol organic modifier to treat it. However, oil absorption indexes of the product are reduced.


2. The titanium dioxide that has been treated with polysiloxane is hydrophobic, which increases its compatibility with plastics resins.


3. Polyols modified titanium dioxide are hydrophilic. They absorb moisture easily, which can affect the plastics’ application performance.


4. In ABS resin systems, titanium dioxide is treated with polysiloxane B. It has the most influence on the mechanical characteristics of plastic products. The material’s tensile strength and impact resistance are best.


5. It is recommended that titanium dioxide be modified using polysiloxane modifiers. Additionally, organic modifiers with different groups should be chosen for different applications to enhance the material’s overall performance.
