Pigment Performance

1. Heat-resistant PVC, PE pigment temperature 160-180 degrees Celsius ABS, PS pigment temperature 250-280 degrees Celsius PP, PA, PET pigment temperature 280 degrees above the general requirements of the pigment heat-resistant time of 4-10 Minute, usually, the higher the temperature, the shorter the heat resistance time.


Phthalocyanine blue pigment temperature 325 degrees Celsius, 10 minutes discoloration

2, the migration resistance of migrant pigments refers to: color plastic products and other solid, liquid, gas and other state, long-term physical contact or work in a particular environment, and the material may have physical and chemical effects, The pigment migrates from the inside of the plastic to the free surface of the article or migrates into adjacent plastic or solvent. Resistance to migration rating Standard Level 1 Level 2 Level 3 Level 4 Level 5 Severe migration Significant migration Yes Migration Minor migration No migration 3. Most inorganic pigments have good light resistance.


4. Weatherability refers to the pigment in the natural conditions of color stability.


5. Titanium Dioxide is divided into: anatase (A) Titanium Dioxide Rutile (R) Titanium Dioxide Titanium Dioxide can improve hiding power, weather resistance, fade resistance, etc. ~ ~ ~ titanium dioxide concentration is low, PP whiteness The content of the increase in the rate of increase, when the concentration of more than 1.5%, the whiteness is no longer increased, from 1% -8%, white tightness increased by 2.8%, indicating that beyond a certain concentration range, increase the amount of titanium dioxide can not increase the white degree. In order to further improve the whiteness, can use fluorescent whitening agent, only a small amount of fluorescent whitening agent can significantly improve the color strength of titanium dioxide. Titanium dioxide, alias: Titanium Dioxide Titanium Dioxide can make plastic effectively scatter visible light and give whiteness, brightness, opacity. PP \ ABS in the concentration of titanium dioxide 1%; PVC in 4%; with the amount of titanium dioxide increased, the hiding power gradually increased, when the concentration is greater than 8% tend to balance. Under normal circumstances, the finer the titanium dioxide particles, the higher the color strength, the stronger the hiding power.


6. Cadmium yellow strong color strength, light resistance, excellent weather resistance, no migration, no bleeding (toxic pigments). This product can be used as a yellow coloring agent for plastic, its bright color, light resistance, excellent heat resistance, solvent resistance, water resistance and alkali resistance is also good, but not acid, coloring, hiding power is not too high.


7. Qunqing has the effect of whitening and toning, it can remove the white products in the yellow shade.
