Non-dewetting PTFE membrane
The non dewetting PTFE membrane provided by MS is made by modifying the e-PTFE membrane with a special coating. Through the unique modification technology of MS, hydrophilic functional groups with strong acid, alkali, and oxidation resistance are formed on the surface of PTFE membrane. Therefore, the surface energy of the modified PTFE membrane is improved, and compared to PTFE membrane, it can maintain a hydrophilic state for a long time in aqueous solution after alcohol infiltration. Strong acid filtration is widely used in the semiconductor industry.
