In short, the general process flow of PTFE microporous filter membrane preparation is: PTFE dispersion resin, booster (material selection), mixing, calendering, biaxial stretching and coiling.

PTFE and ePTFE are polytetrafluoroethylene. PTFE is just the name of a substance, and ePTFE is the abbreviation of expanded PTFE. It is a product processed into porous structure with PTFE resin raw materials. It has the characteristics of porous, light expanded object, filtration, water resistance, ventilation and pressure relief, so it is called ePTFE. Although the physical and chemical properties of the two are similar (the density of ePTFE is lower, the bending performance is better, and the resilience is better), the structure and application are very different!

PTFE microporous filter membrane manufacturer's products are high molecular compounds polymerized by polytetrafluoroethylene. It is a microporous membrane made by special process, calendering, extrusion, biaxial stretching and other methods. The film also has excellent corrosion resistance, aging resistance and high temperature resistance, and the service temperature can reach - 150 ℃ - 250 ℃. It has been widely used in many fields such as electronics, chemical industry, medicine, military, aerospace, clothing, environmental protection and so on.
