Polyester masterbatch quality assurance!

There are two main types of raw materials used in polyester masterbatch: colorant and carrier. According to the different coloring agent and carrier used, some masterbatches also need to add additives. Usually, if the colorant is an organic or inorganic pigment, and the carrier is a low-melting polymer, it is generally necessary to add appropriate additives. If the coloring agent is polyester soluble animal dye, and the carrier is polyester itself, it is generally not necessary to add any additives.
