The full name of the masterbatch is plastic masterbatch. The alias masterbatch is a plastic processing aid developed in the 1980s. It is composed of excess chemical additives, carrier resin and dispersant. Masterbatch is an aggregate obtained by uniformly loading super constant pigment (dye) in resin. Masterbatch refers to the mixing and kneading of various auxiliary agents, fillers and a small amount of carrier resin required for the convenience of operation during the plastic processing and molding process, which are measured, mixed, melted, and extruded through equipment such as an extruder. The granules produced by processing processes such as cutting and pelletizing are called masterbatch. The masterbatch is composed of carrier resin, various fillers and various auxiliaries. The limit of the additive in the masterbatch or the content of the filler is several times to ten times higher than the actual amount required in the plastic product. During the molding process, the ratio of the masterbatch to the matrix resin must be adjusted according to the content of the relevant components in the masterbatch and the amount needed to be added to the actual product. Masterbatch can usually be divided into ordinary filled masterbatch (filled masterbatch for short) and functional masterbatch, such as color masterbatch, anti-fog masterbatch and so on.
Plastic masterbatch has the advantages of uniform dispersion, reducing dust pollution, stabilizing product quality, and improving production efficiency.
Plastic masterbatch is widely used in plastic modification and plastic product processing industries.
