The application of PET masterbatch is very extensive now. Do you know his preparation method? How is it prepared? Next, let's take a closer look at the preparation method of PET masterbatch.


First, the anti-blocking agent and the coupling agent are added to a high-speed mixer with a rotation speed of 500 to 1500 rpm, and mixed for 3 to 5 minutes. The carrier, slip agent, coloring material, and dispersant are added to the high-speed mixer. And antioxidants, mixed at 85 °C ~ 100 °C temperature 5 ~ 30 minutes;


Second: Weigh the components by their weight ratio;


Thirdly, the above mixed material is added into a twin-screw extruder to be fully melt-blended, the melting temperature is controlled at 255° C. to 270° C., and the screw rotation speed is 100 to 300 rpm, which is cut by a twin-screw extruder. Mixing for 10 to 15 minutes, followed by granulation and drying, results in a PET masterbatch according to the present invention.
