A basic introduction to filling masterbatches

Filling masterbatch refers to the plastic processing and molding process, in order to facilitate the operation, the required additives, fillers and a small amount of carrier resin are mixed and mixed first, and the granules and powders prepared are called masterbatches.
Masterbatch is composed of carrier resin, filler and various additives. The limit of additives or filler content in the masterbatch is several times to more than ten times higher than the amount required in the actual plastic products. In the molding process, the ratio of masterbatch to matrix resin must be adjusted according to the content of relevant components in the masterbatch and the amount that needs to be added in the actual product. Masterbatches can usually be divided into ordinary filling masterbatches (referred to as filling masterbatches) and functional masterbatches, such as color masterbatches, anti-fog drop masterbatches, etc. The main component of the filler masterbatch is filler, which is mainly used for the processing and molding of polyolefins (polyethylene and polypropylene), also known as polyolefin filler masterbatch.
