Sinsung PTFE membranes are available in hydrophilic, hydrophobic, unlaminated, and laminated options for a wide range of applications and temperatures.
Hydrophilic membrane filters are usually used with water and aqueous solutions. They can also be used with compatible non-aqueous fluids. Hydrophilic membrane filters are typically not used for air, gas or vent filtration since the filters would block flow if inadvertently wetted, by condensation for example.
Hydrophobic membrane are usually used with compatible non-aqueous fluids. They are also commonly used as air, gas, or vent filters. Hydrophobic membrane are sometimes used with water or aqueous solutions. In these applications, they must first be prewet with a low surface tension, water miscible fluid prior to use.
