Example Embodiment
[0037] Example 1
[0038] Put the commercially available 70% fluorine-containing processing aid PPA 2800, which is composed of tetrafluoroethylene and hexafluoropropylene copolymer, with a weight average molecular weight of 500,000 to 5 million, and 30% pentaerythritol distearate into a high-speed mixer Stir at a high speed to 70-80 ℃, and stir for about 15 minutes. When there is no dust, add the mixed adhesive material to the double-stick cold pressing forming machine, extrude it into a cylindrical masterbatch at room temperature, and vibrate and sieve it. Obtain high-content fluoropolymer processing masterbatch.
Example Embodiment
[0039] Embodiment 2
[0040]Put 80% of fluorine-containing processing aid PPA 2800 and 20% of pentaerythritol distearate into a high-speed mixer to 70-80 ℃, and stir for about 15 minutes. When there is no dust, the mixed adhesive The material is added to a double-bar cold-pressing machine, extruded into a cylindrical masterbatch at room temperature, and vibrated and sieved to obtain a high-content fluoropolymer processing masterbatch.
Example Embodiment
[0041] Embodiment 3
[0042] Put 90% fluorine-containing processing aid PPA 2800 and 10% pentaerythritol distearate into a high-speed mixer to 70-80°C and stir at a high speed for about 15 minutes. When there is no dust, the mixed adhesive The material is added to a double-bar cold-pressing machine, extruded into a cylindrical masterbatch at room temperature, and vibrated and sieved to obtain a high-content fluoropolymer processing masterbatch.
