The full name of plastic masterbatch, also known as masterbatch, is a plastic processing aid developed in the 1980s. It is composed of excess chemical additives, carrier resins and dispersants. The masterbatch is an aggregate obtained by uniformly loading an ultra-constant amount of pigment (dye) in the 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 are first mixed and kneaded, and then measured, mixed, melted and extruded by equipment such as extruders. The granular material obtained by the processing process such as discharging, pelletizing, etc., is called masterbatch. The masterbatch is composed of carrier resin, various fillers and various additives. The limit of additives or filler content in the masterbatch is several to ten times higher than the actual plastic products. 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 that needs to be added in the actual product. Masterbatch can usually be divided into ordinary filler masterbatch (filling masterbatch for short) and functional masterbatch, such as color masterbatch, anti-fogging masterbatch, etc.
