The stability of titanium dioxide product quality is very important to any enterprise. Because the quality stability of titanium dioxide is directly related to the stability of the quality of its downstream users' products. If some indicators of titanium dioxide are unstable, even if a certain indicator of titanium dioxide is greatly improved, this is also a product that downstream users do not want, because if downstream users want to stabilize the quality of their own products, they must adjust the formula accordingly according to the changes in the quality indicators of titanium dioxide, otherwise the product quality will have problems. Therefore, this issue is a matter of great concern to users.

It is very important to choose titanium dioxide products suitable for this application field. There are thousands of types of titanium dioxide in the market, which are mainly divided into two categories: general-purpose and special-purpose. General-purpose products, as the name suggests, are applicable in many fields, but in a specific application field, there is a certain gap compared to special-purpose products in a certain field. Titanium dioxide for plastic masterbatch needs to be changed from hydrophilic to hydrophobic.

Water-based and oil-based coatings cannot be used together with plastics due to their different properties. If special products that are very well used in the plastics industry are used in water-based applications, major quality problems will arise. Therefore, titanium dioxide manufacturers should know which fields their products are suitable for and which are not suitable for, and avoid recommending your company's products to application fields that are not suitable for our products. This will effectively avoid many quality disputes.

Downstream users of titanium dioxide should also have a certain understanding of the products recommended by titanium dioxide manufacturers. They can find out whether there are companies in the same industry using them and how they are using them. And before new products enter the factory, they must conduct small tests to determine whether the product is suitable, so as to reduce unnecessary economic losses caused by improper product selection.

The volatile matter of titanium dioxide is actually the water content. Because there are high energy and hydroxyl groups on its surface, its surface always absorbs a certain amount of water. Reducing the amount of water that can be absorbed on its surface is related to the surface organic treatment of titanium dioxide and the humidity and temperature of the surrounding environment in which it is stored.

The high or low volatile matter of titanium dioxide cannot determine the quality of the product, but depends on its application system. Generally speaking, the high or low volatile matter of water-based systems has little effect on the application, but for oily systems and polyolefin systems, the lower the volatile matter, the better, because high volatile matter will affect its dispersion performance in the system and product quality.

Dispersibility is also called grinding dispersibility or grinding wettability. When used in water as the medium, it is called water dispersibility, and when used in solvents and other coating systems, it is called oil dispersibility. Dispersibility index is an important application index of titanium dioxide.
