Titanium dioxide is a high-quality aluminum modified titanium dioxide widely used in the plastic industry, especially in improving the whiteness, covering power, and weather resistance of plastics. Due to its excellent optical properties, titanium dioxide is often used for coloring and surface coating of various plastic products, which can effectively enhance the UV resistance of plastics and extend their service life.

Titanium Dioxide Can Be Colored and Whitened

Basic principle: tio2 has high whiteness and excellent optical properties, which can effectively scatter and reflect light in plastics. Its white appearance can make plastic products appear bright and white in color. In the process of plastic coloring, it can serve as the main white pigment, and by adjusting its dosage, the whiteness of the plastic can be precisely controlled. For example, in the production of white plastic pipes, plastic sheets, or white household appliance casings, titanium dioxide can provide a pure white effect.

Practical application case: In the production of polyvinyl chloride (PVC) plastic doors and windows, adding an appropriate amount of titanium dioxide can make the color of the doors and windows white and uniform, not only improving the beauty of the product, but also better integrating with the building appearance. Among polystyrene (PS) foam plastic packaging materials, the use of titanium dioxide can make the packaging materials look cleaner and cleaner, and enhance the visual appeal of the product.

Titanium Dioxide Enhances Covering Power

Basic principle: Its high covering power is due to its ability to effectively prevent light from penetrating plastic materials. In plastic, when light shines on the area containing titanium dioxide, the titanium dioxide particles scatter the light, making the underlying material invisible. This is very important for some plastic products that require hiding their internal structure or uneven color. The size of its coverage is related to the particle size, addition amount, and dispersion degree of titanium dioxide in the plastic.

Practical application case: In the production of plastic toys, in order to conceal the possible color differences or internal structural defects of the plastic raw materials themselves, adding titanium dioxide can ensure that the surface color of the toy is uniform and the appearance is smooth. In the manufacturing of plastic parts for car interiors, it can cover the color of the plastic substrate, providing a unified color and texture for the interior.

Tio2 Enhances Weather Resistance

Basic principle: tinox tio2can absorb and reflect ultraviolet (UV) radiation, thereby protecting plastics from UV damage. Ultraviolet radiation can cause the breakage of plastic molecular chains, leading to plastic aging such as yellowing, brittleness, and loss of luster. titanium dioxide is like a "shield", reducing the damage of ultraviolet radiation to the internal structure of plastics and extending their service life.

Practical application case: In outdoor plastic products such as plastic trash cans and plastic gardening tools, the addition of titania tio2 can maintain good physical properties and appearance even under prolonged exposure to sunlight and rain. In the application of plastic building materials such as plastic roof panels and plastic blinds, it can effectively prevent the materials from fading and aging due to ultraviolet radiation, and maintain the long-term stability of the building appearance.

Titanium Dioxide Improves Mechanical Properties

Basic principle: When titanium dioxide is uniformly dispersed in a plastic matrix, it can act as a reinforcing phase to improve the hardness, stiffness, and wear resistance of the plastic to a certain extent. This is because there is an interaction between titanium dioxide particles and plastic molecules, which can restrict the movement of plastic molecular chains, thereby increasing the mechanical properties of the material.

Practical application case: In the application of engineering plastics such as polyamide (PA), polycarbonate (PC), etc., adding titanium dioxide can improve the wear resistance and scratch resistance of plastic components. For example, in components such as plastic gears and plastic bearings that require a certain amount of friction, the presence of titanium dioxide helps to improve the product's service life and performance.
