hydrophilic flat membrane for process filtration
|
|
|
|
Our MicroPES® flat sheet membrane is made from a sulfonated
Polyethersulfone Polymer cast, offered in a wide range of pore sizes from
0.04 to 1.2 µm enabling our customers to meet the requirements of very
different and specific applications.
|
|
|
|
|
|
These range from pre- and/or final-filtration in the food & beverage
industry, process water treatment in microelectronics to applications in the
biotechnology and pharmaceutical industries.
|
|
|
|
MicroPES® flat sheet membranes come in a thickness of 110 µm on rolls and are perfectly suited for use in pleated filter cartridges.
|
|
|
|
Features:
|
High flow rates and throughputs due to a
highly asymmetric pore structure
|
|
|
|
|
Inherently hydrophilic
|
|
|
|
|
Low protein binding characteristics
|
|
|
|
|
Good chemical compatibility
|
|
|
|
|
Available in a wide range of pore sizes

|
|
Double skin on an open anisotropic pore structure
|
|
|
|
|
|
|
|
The highly asymmetrical pore structure of our MicroPES® flat membrane offers a high dirt loading capacity, increasing the filtration performance to give higher throughputs and higher flow rates than symmetrical membranes.
|
|
|
|
Range of pore sizes
|
|
|
|
High flow rates are provided throughout the whole range of poresizes.
|

|
Mechanical properties
|
|
|
|
The double skin construction of all MicroPES® flat membranes provides excellent mechanical properties.
