1. Liangjiang brand-Rutile titanium dioxide?pigment R616?is coated with zirconia and?alumina?in an?inorganicmanner and modified with special organic finishing agent on the surface. With advantages of preferred blue color, good dispersibility, low oil absorption, excellent compatibility and outstanding rheological property under processing, the pigment is particularly applicable to plastic processing. It exhibits outstanding covering power and brightness and is useful to retain the mechanical properties of the finished plastic products. It can be widely used in polyolefin, PVC, ABS, PS, section bar, plate and tube as well as color paste and oil paint.
?
Main features:
?
has good consistency with plastic resin, excellent dispersibility, it can provide good melsedin fluidity, good yellowing resistance in high temperature, bluest bottom phase and good whiteness.
?
Applied range:
?
used in polyolefin, PVC, ABS, PS, section bar, plate and tube as well as color paste and oil paint.
?
Applications:
?
1. Titanium dioxide quality requirements for plastic, PVC and masterbatch

Item | ?Performance |
Hiding power | Lighter and thinner plastic products can be produced using tio2 of good hidinding power |
Whiteness | Decide the appearance of the white or light color palstic products light color or white color |
Dispersibility | Affect the production cost of plastic products as bad dispersibility affects the? smoothness and brightness |
Weather resistance | The outdoors plastic products and plastic doors and windows require the weather resistance of tio2 |
Machinability | Titanium dioxide machinability is the vital key to the production efficiency and cost in the production of white masterbatch (especially the concentration variety) |
Performace impact | Titanium dioxide volume of addition can affects the quality of the plastic products, especially in the condition of larger addition |

Plastic is the second largest parts for titanium dioxide, occupying about 20% of the total world titanium dioxide demands, There are more than 50 brands belongs to plastic specials in the world 500 barands. Requirements for plastic, fine particle, good dispersion performance;Good heat resistance and light resistance,During the heat and the plastic forming process , the finished product does not change color in sunlight exposure and use process. Most of the particle size in plastic is fine. In the plastics, to join titanium dioxide
can improve the heat resistance of plastic products, light fastness, weather resistance, make the plastic products to improve the physical and chemical performance.The strong mechanical strength can extend their life!
The effect of titanium pigment in the plastics industry mainly has two aspects, one is used as the basic white pigment, provide cover (white color); the second is to block uv light, used as uv screen disadvantages agent, used for outdoor plastic products to provide a good weatherability. For the Common plastic,it does not require the weatherability, focuses More on the paint performance requirements.
Due to the characteristics of palstic products, When choosing different, should be taken into account in accordance with the technical requirements of plastic products, mainly to choose anatase or rutile, not same as the coatings, inks, paints.

2. Titanium dioxide compared with other kinds of white pigment :
?
From this sheet, Liangjiang brand rutile titanium dioxide, chlorination process and sulfuric acid process, both has highest coefficient of refraction, highest covering power and tint reducing power. Higher whiteness, higher gloss and better dispersibility.

3.?Rutile Pigments for Plastics
?
Using different experiments we have managed to use TiO2 pigments in plastic industry for years. They have high refractive index and scattering power in the visible region of the spectrum and impart whiteness and opacity in plastics.
When incorporated into plastics, they can provide high durability and increase quality of products.
?
Important applications of this pigment in plastic industry include:
?
? Polystyrene
? Polycarbonates
? PVC
? Polyolefins
? Other Engineering Plastics
This pigment prevents weathering and had special use in PVS profiles.
Rutile pigments used in polycarbonate minimizes the special composition of the polymer in polycarbonate which easily gets wet and decomposes. Using this pigment will meet all customers’ demands regarding optical properties or color grade.
