Microporous Polyethersulfone (PES) Membrane Hydrophilic For Fast Liquid Filtration

Polyethersulfone (PES) membrane is one of the most important polymeric membranes and is widely used in microfiltration fields. PES membranes exhibit outstanding oxidative, thermal, and hydrolytic stability as well as good mechanical properties. The membrane filters always show asymmetric structure and are prepared by a phase inversion method. The membrane structure is influenced by various factors such as the composition of the PES solution, including the concentration of the polymer, solvents, and additives, as well as the temperature of the solution, non-solvent or mixture of non-solvents, and the coagulation bath or the surrounding environment, and so on.

The careful selection of Polyethersulfone material for making PES membranes ensures high mechanical, thermal, and chemical resistances. These properties make PES membranes ideal for use in harsh environments where they need to withstand extreme conditions. Their excellent mechanical properties enable them to maintain their shape and integrity even under high pressure or tension. Along with their high throughput capacity and high flow performance in liquid filtration, the hydrophilic asymmetric polyethersulfone (PES) membranes are well-suited for integration into single-use sterile assemblies such as syringe filters or I.V. infusion sets. Furthermore, PES membranes show excellent thermal stability, which means they can withstand high temperatures without undergoing significant degradation. This property is particularly useful in filtering applications that involve high temperatures, such as wastewater treatment plants or food processing facilities. PES filter membranes can also withstand chemical exposure without losing their performance or causing any harmful effects. In addition to their exceptional stability, PES membranes also exhibit good hydrolytic resistance. This means they can resist breakdown caused by chemical reactions or acids present in the filtration medium. This property is especially important in applications where the filtration may contain organic compounds or other substances that could potentially degrade the membrane.

PES membranes have a wide range of applications in various industries. In healthcare, they are used for medical microfiltration device and sterilization applications to ensure clean and safe products for patients. In industrial settings, PES membranes are used for liquid filtration and sterilization of various fluid streams. In water treatment, they are employed for wastewater purification and remediation processes to remove impurities and contaminants from drinking water sources.

Key features of Polyethersulfone (PES) membranes

• Highly hydrophilic nature: easily absorb and retain fluids.
• Outstanding throughput capacity: can handle large volumes of liquid with ease.
• High flow performance: can maintain consistent filtration efficiency over time.
• Excellent chemical compatibility: pH tolrance range of 1-14, compatible with a range of acids, alkalis, and organic solvents.
• Gamma-irradiatable and autoclavable: remain safe and effective after further agressive processing.
