How to use titanium dioxide for plastic masterbatch?

The use of titanium dioxide for plastic masterbatch mainly includes the following aspects:

Select appropriate particle size: In order to ensure the dispersibility of titanium dioxide during plastic processing, titanium dioxide with moderate particle size should be selected. Generally speaking, titanium dioxide with a particle size between 0.2 and 0.4 μm is an ideal choice.

Control the amount used: The amount of titanium dioxide used should be properly controlled. Excessive use will lead to a decrease in the mechanical properties of plastic materials, while too little use will affect the coloring effect. Generally, the amount of titanium dioxide used is between 2% and 5%.

Use dispersant: In order to ensure the dispersibility of titanium dioxide, some dispersants can be used to assist, such as organic phosphates, polycarboxylates, etc. The appropriate type and amount of dispersant should be selected according to the specific situation.

Control processing temperature: The processing temperature of titanium dioxide should be controlled within an appropriate range, generally below 200°C, to prevent decomposition and deterioration.
‌Uniform mixing‌: Coloring titanium dioxide and plastic materials should be mixed evenly to prevent problems such as uneven color and spots. Equipment such as high-speed mixers or vibrating screens can be used to assist mixing.

‌The characteristics of titanium dioxide for plastic masterbatch include‌:
‌Strong decoloring power‌: It can reduce the amount of addition and save production costs.
‌High whiteness‌: It affects the appearance of light-colored plastic products. Titanium dioxide with different whiteness can be selected according to the appearance requirements of the products.
‌Excellent dispersibility‌: It can reduce production costs and improve the smoothness and glossiness of products.
‌Strong hiding power‌: It helps to produce lighter and thinner plastic products.
‌Excellent heat and weather resistance‌: It ensures the stability and durability of plastic products in high temperature and outdoor environments.
‌Good dry powder fluidity‌: It ensures smooth transmission on the production line and no clogging of the sieve holes.
‌The application of titanium dioxide in plastics also includes‌:

‌Improving the hiding power and whiteness of plastics‌: Titanium dioxide has extremely high whiteness and light reflectivity, and can provide bright white or other required colors.
‌Enhance the weather resistance and UV resistance of plastics‌: It can resist the erosion of ultraviolet rays and extend the service life of plastic products.
‌Improve the thermal stability of plastics‌: Keep the physical properties and appearance of plastics stable under high temperature environment.
‌As a filler to improve the mechanical properties of plastics‌: Enhance the hardness, strength and wear resistance of plastics, suitable for the production of high-performance plastics‌.
