[0002] Masterbatch is a new type of colorant for polymer materials, also known as masterbatch or pigment preparation. It is composed of three basic elements: pigment or dye, carrier and additive. It is made by uniformly loading an extraordinary amount of pigment into the resin. The main purpose of masterbatch is to color plastic products. By mixing a small amount of masterbatch with uncolored resin, the coloring effect of the designed pigment concentration can be achieved. Masterbatch is widely used in the coloring of plastic products and is suitable for various compression molding processes.
