PTFE high temperature filtration membrane is a new type of polymer material.
In terms of production technology, the technical requirements of this kind of membrane are much higher than those of ordinary materials; at the same time, in terms of quality, this membrane also has functional characteristics that other materials do not have.
A long time ago, people have long noticed that polytetrafluoroethylene (PTFE), which has the most outstanding comprehensive properties among polymer materials, has excellent high and low temperature properties, outstanding chemical stability, and good dielectric properties. and hydrophobicity, it is an ideal membrane material for separating microparticles under some harsh conditions. However, the infusible and insoluble characteristics of PTFE have made the technology of manufacturing its microfiltration membrane difficult to solve for a long time, limiting its application and development. In the 1960s, , DuPont Company first used a uniaxial stretching method to make PTFE stretched membrane. Although its micropore size, porosity, and membrane strength were not suitable for use in microfilters, it was widely used as a sealing tape in the future. In the mid-1970s, the United States The PTFE biaxially stretched microfiltration membrane was successfully developed, and was subsequently produced in Japan and Europe. However, so far, only a few companies produce and sell PTFE high-temperature filtration membranes.
It is a manufacturer of polytetrafluoroethylene (ptfe) membrane environmentally friendly materials that specializes in R&D, production and sales.
The PTFE high-temperature filtration membrane we produce is produced 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.
