Polyethersulfone's advantages compared to Polysulfone
- A more stable physical performance
The oxygen ether bond in the PES molecular structure has very high structural stability. The physical and chemical properties of PES are much more stable than materials such as Polysulfone.
- A more remarkable biocompatibility and antithrombosis
- The hydrophilia of Polyethersulfone is much better than that of polysulfone. Through blending with polyvinylpyrrolidone(PVP), the hydrophobic structure of the polyethersulfone will have a better balance with the polyvinylpyrrolidone(PVP). When the connection of the membrane and blood happens, the interaction between the membrane and blood components is greatly reduced so as to reduce protein absorption and does not produce methyl radical. The antithrombosis of the polyethersulfone(PES) membrane material has been confirmed. Therefore, polyethersulfone membrane material has a more remarkable biocompability.
