3M™ DuraPES™ Series microporous Polyethersulfone (PES) Filtration Membrane offers high throughput performance because of the asymmetric pore structure. The evenly distributed pores form an asymmetrical structure with excellent depth filtration characteristic along the thickness of the membrane. The highly asymmetric pore structure of our 3M™ DuraPES™ flat sheet membrane offers a high dirt loading capacity, increasing the filtration performance to give higher throughputs and higher flow rates than membranes with symmetrical pore structure.

The patented pore structure in the cross-section of the 3M™ DuraPES™ Series counteracts rapid clogging in high dirt load applications. This is largely due to the unique pore structure and polymer blend of sulfonated and unsulfonated PES that allows it to remain permanently hydrophilic.
