Organic Modification of Titanium Dioxide and Its Influence on the Properties of Engineering Plastics | Mis-asia

What is Titanium Dioxide?

Titanium dioxide, a valuable inorganic compound chemical pigment, has titanium dioxide as its main constituent. Two process methods are used to make titanium dioxide. One is the sulfuric acid method, and one is the chlorination method. You can use it in papermaking, coatings, and inks.

Engineering plastics’ performance is directly affected by these factors

The defects in titanium dioxide, as well as the strong polarity of the surface make titanium dioxide easy to absorb water. Also, because titanium dioxide is easily agglomerated, its applications in organic polymers are limited due to their easy absorption. The key to wide use of titanium dioxide is surface modification to increase its dispersibility within organic polymers. It is necessary to perform organic modifications in order to increase the wetting, dispersion, and rheological characteristics of titanium dioxide in different dispersion media.


1. Polysiloxane A and B as well as polyol organic modifiers to treat Titani dioxide have no effect on powder’s Lab value. The product also has a lower oil absorption.

2. Hydrophobic properties are a characteristic of titanium dioxide that has been treated with polysiloxane, which increases its compatibility to plastic resins.

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

4. ABS resin systems contain titanium dioxide with polysiloxaneA. It has the most impact on mechanical properties. The material’s impact and tensile strength are also the highest.

5. For improved performance, it is recommended that titanium dioxide be used for engineering plastics. To do this, you should use polysiloxane modifiables.
