PTFE bubble film is widely used
PTFE bubble film is made of polytetrafluoroethylene as raw material and expanded and stretched. A microporous membrane formed by a special process has now been used as a basic material and is used in a wide range of applications.
The bubble point test can only be used for filters of certain specifications. The larger the filter surface area, the higher the impact of diffusive flow through the membrane on the test. If there are a large number of large-pore membrane holes in a large area, the diffusion flow generated by the air flow will cover up the real bubble point, that is, the filter area will affect the observation of the bubble point to a certain extent, because the filter The larger the device, the more air is allowed to pass through per unit time. Therefore, the bubble point test is suitable for use in medium and small-scale filtration systems.
PTFE bubble point membrane has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is used Laminated on various fabrics and substrates by special technology, it can become a new type of filter material. The membrane has small pore size, uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve For advanced purification and ventilation purposes.
