Polysulfone for membrane Market Summary

Polysulfone membrane is a high-performance membrane material widely used in various separation and filtration applications. Its composition primarily includes polysulfone resin and other additives, offering excellent physical, chemical, and mechanical properties. Polysulfone resin can be processed via solvent-based techniques to produce ultrafiltration (UF), osmosis, reverse osmosis (RO), and hollow fiber membranes with high mechanical strength. These products are utilized in energy-saving and water treatment applications, among others.

Thanks to its outstanding chemical stability, mechanical strength, high-temperature resistance, and film-forming properties, polysulfone for membranes has become a core material in the separation membrane industry. It is widely applied in reverse osmosis (RO), ultrafiltration (UF), microfiltration (MF), nanofiltration (NF), and biomedical membranes. In RO membranes, polysulfone typically serves as a support layer, forming a porous structure via phase inversion to provide mechanical reinforcement for the polyamide active layer. Its high-pressure and chlorine resistance significantly enhance the durability of RO membranes in seawater desalination and wastewater treatment. Meanwhile, UF and MF membranes use polysulfone as the base material, leveraging its controllable pore size distribution (UF: 1–100 nm, MF: 0.1–10 μm) and antifouling properties for applications in food and beverage purification, pharmaceutical separation, and industrial wastewater treatment. For NF membranes, polysulfone can be modified via interfacial polymerization or blending to adjust surface charge and nanoscale pore size (1–10 nm), enabling selective retention of divalent ions and small organic molecules, making it highly effective in water softening and dye desalination.

In biomedical applications, polysulfone membranes’ biocompatibility and sterilizability (via gamma irradiation or steam sterilization) make them ideal for hemodialysis, artificial lungs, and drug delivery systems. For instance, hollow-fiber polysulfone dialysis membranes efficiently remove uremic toxins while retaining albumin due to their precisely engineered pore structure. Hydrophilically modified polysulfone membranes further reduce platelet adhesion, improving blood compatibility. Additionally, polysulfone shows potential in gas separation and fuel cell proton-exchange membranes, though sulfonation or nanofiller composites may be required to enhance selectivity or conductivity.

Despite challenges such as hydrophobicity-induced fouling (mitigatable via PEG grafting or amphiphilic copolymer modification), polysulfone membranes remain indispensable in separation technologies due to their overall performance. Future trends will focus on green solvent-based film-forming processes, smart responsive membranes (e.g., pH-/temperature-sensitive types), and emerging applications such as 3D-printed bioscaffolds.

According to the new market research report “Global Polysulfone for membrane Market Report 2025-2031”, published by QYResearch, the global Polysulfone for membrane market size is projected to reach USD 0.19 billion by 2031, at a CAGR of 5.4% during the forecast period.

The market growth of polysulfone for membranes is primarily driven by several key factors. Firstly, the increasingly severe global water scarcity is boosting demand for seawater desalination and wastewater reuse, where polysulfone has become a core support material for reverse osmosis (RO) and ultrafiltration (UF) membranes due to its excellent chemical stability and mechanical strength. Secondly, in the biomedical field, growing demand for high-performance membrane materials in applications such as hemodialysis, drug purification, and biopharmaceutical filtration has made polysulfone membranes the preferred choice due to their biocompatibility and sterilizability. Additionally, the need for efficient, fouling-resistant membranes in industrial separation processes (e.g., food and beverage processing, ultrapure water preparation for electronics) is further driving market development.

Stringent environmental regulations are compelling enterprises to adopt more sustainable separation technologies, and polysulfone membranes, with their durability that reduces replacement frequency, align with green manufacturing trends. Meanwhile, research advancements in emerging applications such as fuel cell proton exchange membranes and gas separation membranes are creating new growth opportunities for polysulfone materials. Although raw material costs remain high, polysulfone membranes maintain a significant position in high-end markets due to their long-term stability and modifiability advantages. Looking ahead, innovations in membrane technology (such as anti-fouling modifications and smart responsive membranes) are expected to further expand the application scope of polysulfone-based membranes.
