What are the main raw materials for polyester masterbatch?

What are the characteristics of polyester masterbatch, follow-up will continue to report for you!

There are two main types of raw materials for polyester masterbatch: colorants and carriers. Depending on the colorant used and the carrier, some masterbatch also needs to add additives. Usually if the colorant is selected organic or inorganic pigments, the carrier is the use of low melting point polymer, generally need to add the appropriate additives. If the colorant is selected polyester soluble lethal dye, the carrier is polyester itself, then generally do not need to add any additives. The former situation and the general plastic masterbatch almost, but the indicators require a higher number of fills, no longer repeat here.

If the preparation of high-grade polyester masterbatch, such as filament-grade polyester masterbatch, is generally believed that the use of polyester soluble dyes, polyester itself as a carrier better.
