What is hydrophilic vs hydrophobic membrane?
Hydrophilic filters posses an affinity for water and can be wetted with almost any liquid. Sterlitech carries a wide variety of hydrophilic membranes, including: • Silver Metal • Polyethersulfone (PES) • Glass Fiber • Polycarbonate Track Etch (PCTE) • Polyester (PETE) • Mixed Cellulose Esters (MCE) • Nylon • Cellulose Acetate Hydrophobic filters lack an affinity for water and are best suited for venting applications. Example of hydrophobic filters are Sterlitech polypropylene membranes and Sterlitech PTFE (Teflon®), either laminated or unlaminated.
