Hydrophobic and Oleophobic PES Membrane

Cobetter polyethersulfone (PES) membrane is made of a modified polyethersulfone polymer cast. The optimized asymmetric structure, enhanced hydrophilicity and high porosity provides extraordinary high flow rate and contaminants retention capacity. The product uniformity results in consistent filtration performance.

Its high mechanical strength supports all kinds of assembling technologies.

Cobetter hydrophobic & oleophobic treated PES membranes have excellent repellency to liquids. It`s an ideal option for venting and gas filtration applications. The gamma irradiation compatibility makes it to be the best alternative of PTFE membrane where gamma irradiation is used for product sterilization.
