PES microporous membrane Polyethersulfone (PES) microporous membranes are naturally hydrophobic. Compared to other filters, PES is easily wetted with water and therefore has a high water flux. PES membrane on the protein adsorption is low and is absolute rated membrane. They are widely used in food, pharmaceutical, water treatment and other fields in clarification and filtration. Tanvi provides excellent PES asymmetric membrane, they are good heat resistance, good mechanical properties and excellent chemical resistance. High filtration rate, low adsorption rate and meet the FDA biosafety standards.Features: high strength High throughput Low dissolution Low protein absorption Excellent hydrophilic Excellent chemical resistance Safe and non-toxic, in line with FDA standards.
