The plastics industry is the second largest user of titanium dioxide, the fastest growing area in recent years, with an average annual growth rate of 6%. Among the more than 500 titanium dioxide grades in the world, more than 50 grades are plastic-specific.

The application of titanium dioxide in plastic products mainly utilizes its high hiding power, high tinting reduce power and other pigment properties. It can also improve the heat resistance, light resistance and weather resistance of plastic products and protect plastic products from UV light. Invasion, improve the mechanical properties and electrical properties of plastic products. The quality requirements of titanium dioxide on plastic products are:

1, Hiding power: titanium dioxide with good hiding power, the plastic products produced are lighter and thinner;

2,Whiteness: determines the appearance of light-colored or white plastic products;

3,Dispersion: Affecting the production cost of plastic products, poorly dispersed titanium dioxide will affect the smoothness and brightness of the products in plastic products;

4,Weatherability: Plastic products and plastic doors and windows used outdoors must ensure the weather resistance of titanium dioxide.

Masterbatch

Titanium Dioxide is used as a white pigment, which has the advantages of non-toxicity, chemical stability, high hiding power, and good dispersion.

• Typical masterbatch production processes such as:

1,Titanium tinting power: determine the amount of titanium white used in the same plastic product color (Achromatic Power)

2,The whiteness of titanium dioxide: the appearance of light-colored (white) plastic products with the same content of titanium dioxide;

3,Dispersion of Titanium Dioxide: Affects the production cost of pigments and the appearance and gloss of plastic products;

4,Titanium dioxide processing performance: It affects the production cost of masterbatch.
