Color Masterbatch coloring

Masterbatch coloring is the most widely used plastic coloring method nowadays. It is used to make plastic products by simply mixing the colorant dispersed in the carrier with the colour masterbatch resin. The pigment is mixed with the coloring agent and mixed with the coloring agent to granulate into colored plastic.

Dry powder coloring: the mixture of powdery coloring agent and natural resin is directly used to make plastic products.

Pigment selection of Masterbatch

Different functional masterbatches, in the selection of pigments, the performance is different, the following are introduced separately, functional masterbatches how to choose pigments:

The pigments used for heat-resistant masterbatch can withstand the temperature in the production process of polypropylene fiber and keep its properties stable. The temperature-resistant temperature is generally required to be above 270 ~ 280 C.

The pigment used for dispersive masterbatch should be well dispersed and evenly dispersed in the masterbatch, and the dispersant used will not reduce the quality of polypropylene fiber.

Brightness polypropylene solution coloring has many uses, including bedspread substrate and knitted fabrics, requires bright colors. Because organic pigments are bright and bright, and easy to color, so the use of organic pigments for the above purposes.

The light resistance of some pigments under the action of light has a photosensitive effect, make the colored fiber fade and brittle damage, and the light resistance of pigments is basically related to its chemical structure, so in the production of masterbatch should pay full attention to the light resistance of pigments, light resistance pigments need to be used, can consider adding ultraviolet absorbent.
