PTFE hydrophilic filter membranes are modified from hydrophobic PTFE and include: PTFE hydrophilic smooth membranes and PTFE hydrophilic composite membranes.
PTFE hydrophilic smooth membranes possess the following characteristics: excellent hydrophilicity, high hydrophilic stability, and good chemical resistance and temperature tolerance. They can be widely used for filtering various liquids, including corrosive liquids such as strong acids and strong bases.
PTFE hydrophobic filter membranes are made from naturally hydrophobic polytetrafluoroethylene polymer and include: PTFE hydrophobic smooth membranes and PTFE hydrophobic composite membranes.
Hydrophilic polyvinylidene fluoride (PVDF) membranes are hydrophilically modified based on hydrophobic PVDF membranes, reducing the surface contact angle and enhancing hydrophilicity. Hydrophilic PVDF membranes exhibit extremely low protein adsorption while maintaining exceptionally high water flux and broad chemical compatibility. Consequently, PVDF membranes are frequently used for filtering culture media and other protein solutions. We offer filter membranes with pore sizes ranging from 3 μm to 0.1 μm.
