Polytetrafluoroethylene (PTFE) is commonly known as "the king of plastics". Its special molecular structure makes it invulnerable to all poisons (it will not change when boiled in aqua regia). It can work for a long time at -190~250 °C and is widely used. In environmental protection, sealing, aerospace and other fields.

The PTFE membrane filter material can control the emission concentration below 10mg/m3, which fully meets the latest emission requirements. PTFE membrane filter material has the following advantages:

①High filtration efficiency. The test results of ETS Company in the United States show that the emission concentration of PTFE membrane filter material to PM2.5 is 0, which can truly achieve zero emission of PM2.5.

②The surface filtration is easy to clean the dust, the dust removal effect is good and the stability is high. Since the PTFE-coated filter material realizes surface filtration and has extremely low surface energy, it has better peelability from dust and less resistance loss compared with traditional filter materials.

③Good ventilation performance. The porosity of PTFE microporous membrane is as high as 85% or more, which solves the problem of air permeability well.

④Long service life, due to the excellent acid and alkali resistance and high temperature resistance of PTFE, it has a higher service life than other materials. In addition, due to surface filtration, the number of times of cleaning is large, and the wear and tear will be appropriately reduced, which greatly improves the service life of the filter bag. .

⑤ Low operating cost and low operating energy consumption.
