Product Introduction
PTFE hydrophilic filter membranes are modified from hydrophobic PTFE and include: PTFE hydrophilic smooth membranes and PTFE hydrophilic composite membranes.
The PTFE hydrophilic optical film features excellent hydrophilicity, high hydrophilic stability, and good chemical resistance and temperature resistance. It can be widely used for filtering various liquids, including corrosive fluids such as strong acids and strong bases.
The PTFE hydrophilic composite membrane is fabricated by thermally laminating a hydrophilic, optically clear ePTFE film with supporting materials such as PP and PET, followed by surface hydrophilization treatment. It boasts exceptional chemical compatibility, strong hydrophilicity, and high flux, and is resistant to nearly all solvents. It is widely used in sterilizing filtration applications, including the filtration of organic solvents, mixed solvents, acidic or alkaline solutions, and strongly oxidizing solutions.
