Fluoroplastics (such as PTFE, FEP, PFA, ETFE, etc.) feature high melting points, high viscosity, and strong corrosion resistance. During extrusion, they readily produce gels and impurities, imposing stringent demands on the screen changer s high-temperature resistance, corrosion resistance, sealing performance, and screen-changing efficiency. The single-column screen changer offers compact design, user-friendly operation, rapid screen changes, and minimal melt pressure fluctuations. These advant
