Plastic is a mixture of resin, plasticizer, filler and coloring
agent, it has light weight, corrosion resistance, friction
resistance, high mechanical properties, good electrical insulation,
easy processing, beautiful and other characteristics, can be used
as structural materials, insulation materials and corrosion
resistant materials, in the national economic departments, military
industry and cutting-edge science and technology has been widely
used
In order to make plastics have beautiful colors, a certain amount
of color is often added to plastics. The requirement for the color
is that it is easy to color and disperse during processing, and
does not react chemically with other components in the plastic. Due
to the high whiteness of tio2, large achromatic power, with good
opacity and chemical stability, with titanium dioxide instead of
Lide powder, the amount of white pigment can be reduced by 2 to 3
times to produce white or color plastic necessary coloring filler,
is the best white pigment. When used in combination with other
pigments, it can form beautiful bright colors, because toys and
food utensils are non-toxic.
