The asymmetric pore structure of 3M™ MicroPES™ Flat Sheet Membrane provides high throughput performance in a wide range of applications due to different pore sizes available.
The evenly distributed pores form an asymmetrical structure along the thickness of the membrane with pronounced depth filtration characteristics. 3M™ MicroPES™ Flat Sheet Membrane is used in various applications requiring high retention. It can be processed using common pleating and welding techniques and is also available in a wide variety of pore sizes to meet the needs of various specific applications. Chemically enhanced backwash with chemical cleaners, such as hydrochloric acid, citric acid, acetic acid, sodium hydroxide, or sodium hypochlorite, does not affect the mechanical stability of the membrane. 3M™ MicroPES™ Flat Sheet Membrane offers proven throughput performance due to its asymmetric pore structure.
