Highlights

3M™ MacroPES™ is available in large nominal pore sizes of 3µm and 5µm
Negative zeta potential of the membrane
Withstands dilute acids and bases (pH 2-12), and a many different solvent
Chemical enhanced backwash with common chemical cleaners, such as hydrochloric acid, citric acid formic acid, acetic acid, sodium hydroxide or sodium hypochlorite does not affect the mechanical stability of the membranes
3M™ MacroPES™ Flat Sheet Membranes can be sterilized by ETO- and gamma-irradiation
Good processability due to high mechanical strength
Low tendency to blocking
High flux results on 3M™ MacroPES™ series
Made from Polyethersulfone
Good thermal welding and good bond ability
Pores are evenly distributed over the surface of the membrane
Excellent wetting properties due to polar surface

The 3M™ MacroPES™ Flat Sheet Membranes pore structure in combination with the relatively open surface is responsible for the high filtration performance with a low tendency to blocking.

Due to the slightly asymmetrical distribution of the pores, the retention layer lies protected inside the cross-section, while the surface with its open pore structure ensures high filtration performance. The material used is characterized by excellent wetting properties due to polar surface. MacroPES Flat Sheet Membranes possess good thermal welding properties for applications in various industries.
