As one of the most popular filter materials in modern times, polytetrafluoroethylene microporous membrane can solve many problems in people’s lives. Today we will fully understand this material.
Polytetrafluoroethylene (PTFE) material, commonly known as the “king of plastics”, is a polymer compound polymerized by tetrafluoroethylene. It has excellent high temperature resistance, oxidation resistance, alkali resistance, hydrophobicity, and non-adhesion performance.
The polytetrafluoroethylene microporous membrane is prepared by a biaxial stretching process. It has a microporous structure with staggered fibers. It has high porosity and small and uniform pore diameter. Therefore, the ptfe microporous membrane can be used under low resistance. Can achieve higher efficiency.
The filtration mechanism of ptfe microporous membrane is a surface filtration mechanism, which can easily remove dust. The membrane pore size is small and uniform, the micropore structure is stable, the porosity can reach 80%~90%, the filtration efficiency can reach 99.999995%, and the filtration accuracy can Reach U15 level and above, even reach U17 level.
At the same time, the surface is water-repellent and has a very high water pressure resistance, so it has high waterproof performance.
The protection against viruses in liquids is mainly based on the low surface tension of the PTFE film and the high water pressure resistance of the composite film, making it difficult for droplets to adhere, wet or penetrate.
The polytetrafluoroethylene microporous membrane processed by biaxial stretching technology is widely used in air dust removal due to its wide operating temperature range, small friction coefficient, stable chemical properties, low surface energy, microporous structure, etc. It is widely used in environmental protection and chemical fields such as air sterilization and water filtration. It also has a unique network microporous structure, making it widely used as functional clothing materials such as waterproof, breathable, windproof and warm, and protective.
