Polyester masterbatch is a kind of masterbatch. So, do you know about this masterbatch? First of all, you need to know the meaning of masterbatch: coloring by a high proportion of pigments or additives and thermoplastic resin, well dispersed plastic. The selected resin has good wetting and dispersing effect on the colorant and has good compatibility with the coloring material. Namely: Pigment + Carrier + Additive = Masterbatch.

Polyester masterbatch is mainly made of polyester resin, and then mixed with carbon black or other color pigments to cause small particles to be used for dyeing other plastic products.

There are two main types of raw materials used in polyester masterbatch: colorants and carriers. Depending on the colorant and carrier used, some masterbatches also require the addition of auxiliaries. Usually, if the coloring agent is an organic or inorganic pigment, the carrier is selected from a low melting point polymer, and it is generally necessary to add a suitable auxiliary agent. If the colorant is a polyester soluble dye and the carrier is the polyester itself, it is generally not necessary to add any additives. The former case is similar to the general plastic masterbatch, but the requirements for each index are higher, and will not be repeated here. If high-end polyester masterbatch, such as filament-grade polyester masterbatch, is prepared, it is generally considered to be a polyester-soluble dye, and the polyester itself is preferred.
