Simply speaking, the general process flow for the preparation of ptfe microporous filter membrane is: polytetrafluoroethylene dispersion Resin, booster (material selection), mixing, calendering, biaxial stretching, and coiling.
PTFE and ePTFE are both polytetrafluoroethylene, PTFE is just the name of a substance, and ePTFE is the abbreviation of expanded PTFE. It is a product made of PTFE resin raw material processed into a porous structure. It has the characteristics of porous, lightweight, filtering, water blocking, ventilation and pressure relief of expanded objects, so it is called ePTFE. Although the physical and chemical properties of the two are similar (ePTFE has lower density, better bending performance, and better resilience), their structures and uses are very different!
PTFE microporous filtration membrane manufacturer’s products are microporous membranes made of polymer compounds made of polytetrafluoroethylene using special processes such as calendering, extrusion, and biaxial stretching. The film also has excellent corrosion resistance, aging resistance and high temperature resistance, and the operating temperature can reach -150℃ to 250℃. It has been widely used in many fields such as electronics, chemical industry, medicine, military, aerospace, clothing, environmental protection and so on.
PTFE membrane manufacturer specializes in the production of PTFE microporous filtration membranes. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membranes; The materials of the products produced are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
