How does the film functional masterbatch choose the right pigment?

Different film functional masterbatch have different properties when pigments are selected. The following describes the function of film functional masterbatch:

The pigments selected for the heat-resistant masterbatch, the most basic requirements can withstand the temperature during the production of polypropylene fibers, to maintain the stability of its performance. The temperature resistance temperature is generally required to be 270~280°C or more.

The pigment for disperse masterbatch should be excellent in dispersibility and uniform in the masterbatch, and the dispersant used will not reduce the quality of the polypropylene fiber. Otherwise, the quality of the raw liquid can not be produced, and the operation is unstable. It is easy to break or produce abnormal fibers when drafting fibers.

Brightness polypropylene coloring has a variety of uses, including bedcloth fabrics and knitted fabrics, which require bright colors. Because organic pigments are bright and bright, and easy to color, organic pigments are used for the above purposes.

Light resistance Some pigments have a photosensitizing effect under the action of light, which causes the colored fibers to fade and be brittle. The light resistance of the pigment is basically related to its chemical structure. Therefore, attention should be paid to the light fastness and light resistance of the pigment when making the masterbatch. When the pigment needs to be used, it is possible to consider adding a UV absorber.

The pigment used in the stability masterbatch has excellent stability to the colored polypropylene fiber. That is to say, the pigmented polymer does not react with the fiber after prolonged contact with heat, light or high temperature to form a new chemical base. The group makes the polymer performance low.
