The application range of titanium dioxide for plastics is expanding or expanding.

News: General plastic with
tumium dioxide
generally does not go through surface treatment, because the use of conventional hydrated aluminum oxide such inorganic coating of titanium white powder, in the relative humidity of 60%, its adsorption balance water in about 1%, when the plastic at high temperature extrusion processing, moisture evaporation will lead to smooth plastic surface gas holes, this non-inorganic coating of titanium dioxide, generally to be treated with organic surface.
Because the plastic with titanium dioxide powder and
paint
with titanium dioxide powder is different, the former is in a low polarity resin, through shear processing mixing, organic surface treatment of titanium dioxide, in the appropriate mechanical shear force, can be better dispersed.
Titanium dioxide in plastic products, in addition to the use of its high cover, high coloration and other pigment properties, it can also improve the plastic products heat resistance, light resistance, weather resistance, so that plastic products from UV light attack, improve the mechanical and electrical properties of plastic products.
Most plastics with titanium white powder particle size is relatively fine, usually paint with titanium white powder particle size of 0.2 to 0.4 m, and plastic with titanium white powder particle size of 0.15 to 0.3 m, so that you can obtain the blue background phase, most of the resin with yellow phase or easily yellow resin has a masking effect.
