PES hydrophilic membrane


PTFE hydrophilic membrane

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 membrane

PTFE hydrophobic filter membranes are made from naturally hydrophobic polytetrafluoroethylene polymer and include: PTFE hydrophobic smooth membranes and PTFE hydrophobic composite membranes.


PVDF hydrophilic membrane

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.

How can the hydrophilicity of polymeric microfiltration membranes be improved?

To enhance the hydrophilicity of polymeric microfiltration membranes, the key is to reduce their surface contact angle (a contact angle θ < 70° is considered hydrophilic) and improve surface wettability.

The country has released the “Pharmaceutical Industry Development Plan,” which focuses on supporting the development of innovative drugs and CDMO services, presenting new opportunities for the high-end filtration consumables market.

Yes, this assessment is highly consistent with the current policy orientation and industrial development trends in China’s pharmaceutical sector. In recent years, the Chinese government has intensively introduced a series of top-level plans, explicitly identifying innovative drugs and CDMOs (Contract Development and Manufacturing Organizations) as strategic priorities. Consequently, high-end filtration consumables—such as ultrafiltration membranes, nanofiltration membranes, virus removal filters, and single-use filtration systems—that serve as the “infrastructure” supporting biopharmaceutical production are now experiencing unprecedented growth opportunities.
