PRE-DISPERSED PIGMENT – EASY AND CLEAN TO USE

Our pre-dispersed pigment contains 75%-85% pure powder pigments that are dispersed with dispersion agent, even higher than BASF Eupolen (TM) products, but we are using different technology. It is used for high quality masterbatch production, applies for fiber, film, injection molding and blow molding. It can be also called semi-masterbatch. It is characterized with best dispersion and excellent tint strength (15-30% higher) through pre dispersion treatment such as fine grinding and stabilization of high quality pure powder pigments.

The advantages of pre-dispersed pigment in replace of pure pigment powders:

1. High dispersion, 15–30% higher than pure powder pigments because the pure powder pigments are totally dispersed;

2. Dust free. The products are formed as 2–3mm granule, suitable for higher environment protection requirements.  Shorten the equipment cleaning time and easily shift the color in the process;

3. High pigment concentration 75%-85% with low wax content, easy to formulate masterbatch recipe;

4. Medium to highest light fastness, heat stability and dispersibility;

5. They meet all possible coloristic requirements;

6. Compatible with most polymers such as PE, PP, EVA, ABS and many more resins；

7. Less production equipment required to produce masterbatch than with pure powder pigments. No need high shear mixing prior to extrusion; Easily dosed by all types of feeders；

8. Increase the production efficiency, suitable for automatic and big scale production; No need big amount of stock and decrease the cash flow preparation;

9. The final products are characterized with high glossiness and color strength.
