The polytetrafluoroethylene filter bag membrane has the characteristics of uniform fiber distribution, large dust holding capacity, low resistance, and high strength, and is an ideal air filtration material.
The technical indicators of filter paper can be mainly divided into two aspects. One is the filtration characteristics of the filter paper, and the other is the physical properties.
Filtration characteristics include air permeability, air resistance, maximum pore size, and average pore size.
The polytetrafluoroethylene filter bag membrane is made of polytetrafluoroethylene. It is expanded and stretched to form a microporous film. This film is coated on various materials using a special process. On fabrics and substrates, it becomes a new type of filter material. The membrane has small pore size (0.05~0.45μm), uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve purification and Ventilation purpose.
