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.
Nutzen und Einsatzmöglichkeiten von 3M™ MacroPES™ 25 Series Flat Sheet Membrane, 254 mm Roll/Variable Pack
- 3M™ MacroPES™ Flat Sheet Membranes can be sterilized by ETO- and gamma-irradiation
- 3M™ MacroPES™ is available in large nominal pore sizes of 3µm and 5µm
- 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
- Excellent wetting properties due to polar surface
- Good processability due to high mechanical strength
- Good thermal welding and good bond ability
- High flux results on 3M™ MacroPES™ series
- Low tendency to blocking
- Made from Polyethersulfone
- Negative zeta potential of the membrane
- Pores are evenly distributed over the surface of the membrane
- Withstands dilute acids and bases (pH 2-12), and a many different solvent
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.
