Polyester masterbatch is a kind of masterbatch, so do you know this kind of masterbatch? First of all, you need to know the meaning of masterbatch: a high proportion of pigments or additives and thermoplastic resin, well-dispersed plastic coloring Agent, the selected resin has good wetting and dispersing effects on the colorant, and has good compatibility with the material to be colored. That is: pigment + carrier + additive = masterbatch.

The polyester masterbatch is mainly composed of polyester resin, and then mixed with carbon black or other color pigments to extrude, resulting in small particles used for dyeing other plastic products. It is based on polyester resin, and then mixed with carbon black or other color pigments to extrude them into small particles for dyeing other plastic products.

There are two main types of raw materials used in polyester masterbatches: colorants and carriers. Depending on the colorant and carrier used, some master batches need to be supplemented with additives. Generally, if the colorant is selected from organic or inorganic pigments, and the carrier is selected from a low-melting point polymer, an appropriate auxiliary agent is generally required. If the colorant uses polyester soluble animal dyes and the carrier is polyester itself, then no auxiliary agent is generally added. The former situation is similar to the general plastic masterbatch, except that the requirements of the indicators are higher, and we will not repeat them here. If high-specification polyester masterbatches are prepared, such as filament-grade polyester masterbatches, it is generally considered that polyester soluble dyes are used, and polyester itself is a better carrier.
