Polyester masterbatch, in the production and application of a lot of benefits, multi-application clothing ah, plastic ah and many other areas, then you know how to use polyester masterbatch?

Polyester masterbatch use is very simple, just according to the provisions of the ratio of resin particles mixed with the manual mix can be.

In the operation of the equipment should pay attention to the following questions:
1.1. Injection Molding Machine or Extruder Mixing chamber generally has a plurality of temperature zones, in which the temperature near the blanking port should be slightly higher, in order to allow the masterbatch to melt rapidly after mixing with the plastic resin Mixed evenly, which is conducive to color masterbatch in the products in a good dispersion.
1.2. Appropriate application of the back pressure of the injection molding machine, which can improve the mixing effect of the screw, favorable dispersion of the pigment, the side effect of the application of back pressure is to slow down the injection rate.
1.3. Extrude the die temperature of the extruder to increase the brightness of the product.

What are the main raw materials for polyester masterbatch?
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 Bale, 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.
