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 absorb water during production, storage, transportation and storage. This limits its use in organic polymers. The key to wide-spread titanium dioxide use is effective 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. Use of polysiloxane, polysiloxane, or polyol organic modifier to treat titanium dioxide has little effect on the Lab values of the powder. The oil absorption index of this product is also 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 polysiloxaneA. The material’s impact strength and tensile characteristics are best.
5. It is suggested that titanium dioxide be modified using polysiloxane modifiers. Additionally, organic modifiers with different groups should be chosen according to various application systems in order to enhance the material’s overall performance.
