Application of Titanium Dioxide in Masterbatch

Plastic masterbatch is a highly concentrated, high-efficiency color preparation, that is, a pigment. The pigment is evenly distributed in the carrier resin at an extraordinary concentration and forms particles of a certain particle size. It is mainly composed of core layer, coupling layer (coupling agent or surfactant), dispersion layer (lubricant or dispersant), mixing layer (carrier resin), etc. It is used as a dye in plastics and is widely used in the production of plastic products such as film blowing, injection molding, hot pressing, and injection molding. Masterbatch has excellent coloring effect, is easy to use, saves energy, and is free of dust and sewage when used, so it is favored by users. The development speed of masterbatch is very fast. In addition, the production process of masterbatch is simple, and the product competition is becoming increasingly fierce.

Masterbatch can be used to color PVC, polyethylene, polypropylene, polystyrene and ABS plastics. Its main ingredients are pigments, resins, dispersants, volume pigments, fluorescent whitening agents, antioxidants, anti-UV agents, antistatic agents, toughening agents, brighteners, etc. Titanium dioxide is used as a white pigment and has the advantages of non-toxic, stable chemical properties, high hiding power and good dispersion.

Masterbatch is used as an industrial raw material, and its performance is usually reflected in subsequent product applications (such as film blowing or injection molding). Therefore, the performance of titanium dioxide in color masterbatch is also mainly reflected in the application process of color masterbatch. Mainly reflected in the following aspects:

1) The coloring ability of titanium white: determines the amount of titanium white used for the color of the same plastic product;

2) Whiteness of titanium dioxide: determines the appearance of light-colored (white) plastic products with the same titanium dioxide content;

3) The dispersion of titanium dioxide: affects the production cost of colored particles and the appearance, gloss and other indicators of plastic products;

4) The processing performance of titanium dioxide: affects the production cost of masterbatch.
