PTFE films are mainly divided into two types: microporous films and turning films.
The main difference between the two is that the microporous membrane is breathable, which is produced by two-way stretching; the turning membrane is made by lathe cutting and is not breathable.
PTFE bubble point membrane 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.
