Introduction to Hydrophilic PES Membrane
Hydrophilic Polyethersulfone (PES) membrane is a high – performance filtration membrane material. PES is a thermoplastic polymer known for its excellent chemical resistance, high mechanical strength, and good thermal stability. The hydrophilic modification of PES membranes endows them with enhanced water wettability, which is crucial for applications in aqueous systems. These membranes can effectively separate particles, macromolecules, and microorganisms from liquids. They are widely used in various fields such as water treatment, biotechnology, pharmaceutical production, and food and beverage processing. Hydrophilic PES membranes offer high flow rates, low protein binding, and high retention efficiency, making them a popular choice for many filtration needs. Hydrophilic PES Membrane
