In applied research, polytetrafluoroethylene composite materials are a more active area of research in recent years. They can reduce membrane clogging, extend service life, and increase processing capacity.
From the perspective of import and export, China’s PTFE filter membranes and clothing membranes are mainly exported; imports are mainly finished products, such as coated filter bags, finished fabrics, and PTFE components for electronic automobiles. Affected by the global COVID-19 epidemic in 2020, many PTFE microporous membrane composite membrane manufacturers switched to producing masks, protective clothing and other products, so the industry as a whole still maintained a high growth rate.
Polytetrafluoroethylene composite material is a membrane material with excellent performance for filtering and separating particles. It can be used for atmospheric dust removal, air purification, etc. The pore size of the membrane can be controlled to 0.2um, and the porosity can reach more than 88%. It can be combined with various filter materials such as needle felt, machine-made cloth, non-woven fabric, glass fiber, etc. to obtain surface filtration. The high-performance coated filter material makes the coated filter material have the characteristics of high peel strength, large air permeability, and uniform pore size distribution.
Polytetrafluoroethylene composite material is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux. The material is resistant to high temperatures, strong acids and alkali, 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.
