ptfe Hypa filter membrane has high porosity
PTFE Hypa filter membrane is a polymer compound polymerized by tetrafluoroethylene. It is stretched in two directions It is prepared by the stretching process and has a microporous structure with staggered fibers. It has high porosity and small and uniform pore diameter.
HEPA (High efficiency particulate air Filter), which means high-efficiency air filter in Chinese, is a filter that meets HEPA standards and has an effective efficiency of 99.7% for 0.1 microns and 0.3 microns. , the characteristic of HEPA net is that air can pass through, but fine particles cannot. It can remove more than 99.97% of particles with a diameter of 0.3 microns (1/200 of the diameter of a hair) and is the most effective filtering medium for smoke, dust, bacteria and other pollutants.
PTFE Hypa filter membrane is a perfluorinated polymer obtained by polymerization. This material can be used for a long time in the range of -200℃ to 250℃. In its molecular structure, the carbon atom is surrounded by four fluorine atoms. Since the covalent radius of the fluorine atom (0.064nm) is larger than the radius of the hydrogen atom (0.028nm), the fluorine atoms can be arranged to surround the carbon chain, and Because fluorine atoms repel each other, the entire macromolecular chain does not have a zigzag shape like a hydrocarbon molecular chain.
It is a high-tech enterprise focusing on the research and development, production and sales of PTFE Hypa filter membrane. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a cooperation with the top 500 companies in the United States. Partner; the products we produce are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity. Moreover, we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
