Controllable filtration accuracy: the pore size of ePTFE membrane can be adjusted for obtaining different bubble point pressures, in order to get the different filtration accuracy.
Microporous distribution uniform: the microporous of ePTFE membrane is distributed uniform,ensuring complete interception of impurities such as bacteria.
Excellent chemical resistance: broad chemical applicability and biosafety.
The ePTFE membrane can be made into hydro-phobic and hydrophilic.
High biosafety: it passed 100% integrity test and met the requirements of American HIMA bacterial retention experiment

The ePTFE membrane for liquid filtration is prepared by biaxial stretching technology. The micro porous of membrane distribution is very uniform, and the pore size is adjustable within the range of 0.1l-10 μm. It can effectively intercept bacteria or particles of specific sizes and has the characteristics of high flow rate, high intensity and good biological safety. The hydrophilic ePTFE membrane performs well in water filtration applications.
