PTFE filter material has the characteristics of stable chemical properties, high filtration efficiency, thorough dust removal, high temperature resistance, and corrosion resistance.
In addition, the membrane is loved by everyone for its wide application range, long life, low energy consumption and low cost.
So it is deeply loved by industries such as medicine, clothing, and industry.
PTFE (Polytetrafluoroethylene) is “polytetrafluoroethylene” and is generally called “non-stick coating” or “easy-to-clean material”.
This material is acid-resistant, alkali-resistant, resistant to various organic solvents, and is almost insoluble in all solvents.
At the same time, PTFE is resistant to high temperatures.
PTFE filter material is made of polytetrafluoroethylene as the main raw material and adopts wet molding process. It has the characteristics of uniform fiber distribution, large dust holding capacity, low resistance and high strength. It is an ideal air filter 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.
Physical properties include basis weight, thickness, stiffness, corrugation depth, bursting strength, resin content, etc.
PTFE filter material is prepared using unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
