PES Membrane - Hydrophobic

This hydrophobic PES membrane is manufactured through a specialized hydrophobic modification of sterilizing-grade hydrophilic PES material. It is designed for efficient gas filtration and sterile venting, effectively preventing liquid intrusion and condensation blockage. Unlike conventional gas filtration media, it maintains consistent mechanical performance after high‑dose gamma irradiation, offering reliable suitability for air sterilization processes that require radiation‑based sterilization.

This hydrophobic PES membrane offers enhanced air permeability over traditional PVDF materials while demonstrating stronger gamma tolerance and greater post-sterilization stability compared to PTFE membranes. It effectively captures particulate contaminants and microorganisms in gaseous streams, making it well-suited for sterile air and gas filtration applications. The membrane maintains reliable system sterility without compromising ventilation efficiency, providing durable performance in demanding filtration environments.
