Description

Technical Field

[0002] The full name of masterbatch is masterbatch, also called color seed. It is a new type of colorant specially used for polymer materials, also called pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading an extraordinary amount of pigment into the resin. It can be called pigment concentrate. After the masterbatch is granulated, there will be excess material falling from the masterbatch due to process reasons. Therefore, the excess material will be removed after the masterbatch is granulated.
