Color masterbatch coloring

Masterbatch coloring is now the most commonly used plastic coloring method. The coloring agent dispersed in the carrier, with the masterbatch color resin simple mixed for the manufacture of plastic products. The pigment is mixed with the colorant and the colorant to be granulated into colored plastic, and is used in the molding process. Dry powder coloring: the powdery colorant and color resin evenly mixed directly after the manufacture of plastic products.

Color Masterbatch pigment selection

Different functional masterbatch, the choice of paint, the performance is different, the following were introduced under the functional masterbatch how to choose the pigment:

 Heat-resistant masterbatch selected pigments, the most basic requirements of the polypropylene fiber production process can withstand the temperature, to maintain its performance stability. Temperature temperature is generally required for more than 270 ~ 280 ℃.

Dispersible masterbatch pigment should be excellent in dispersibility, and in the masterbatch to be dispersed evenly, and the use of dispersants will not reduce the quality of polypropylene fiber, otherwise it can not produce good quality liquid stained liquid, the operation is not stable , It is easy to break or produce abnormal fibers when drawing fibers.

Brightness Polypropylene liquid coloring has a variety of uses, which are used for bedspreads and knitted fabrics, require bright colors. Because organic pigments are bright and bright, and easy to color, so that the use of organic pigments for the use of the above.

 Light resistance In the light of the role of some pigments have photosensitive effect, so that coloring fiber fade and fragile, and the light resistance of the pigment is basically related to its chemical structure, so the production of masterbatch should pay full attention to the light resistance of light, light Of the pigment need to be used, you can consider adding UV absorbers.
