Masterbatch, full name plastic masterbatch, alias masterbatch, is a plastic processing aid developed standing up in the 1980s, it is composed of excess chemical additives, carrier resin and dispersant, etc. . The masterbatch is an aggregate obtained by uniformly supporting an excessive amount of a pigment (dye) in a resin. Masterbatch refers to the process of plastic processing, in order to facilitate the operation, the required various additives, fillers and a small amount of carrier resin first mixed, measured through the extruder and other equipment, mixing, melting, extrusion. The pellets obtained during the processing of pelleting are called master pellets. Masterbatch consists of carrier resin, various fillers and various additives. The limit of the adjuvant in the masterbatch or the content of the filler is several to ten times higher than that in the actual plastic product. In the molding process, the proportion of the masterbatch and the matrix resin must be adjusted according to the content of the relevant components in the masterbatch and the amount of the actual product to be added. Masterbatch can usually be divided into ordinary filling masterbatch (abbreviated as filling masterbatch) and functional masterbatch, such as masterbatch, anti-mist dripping masterbatch and so on.
