PSU Disk

PSU Disk, made from polysulfone, provides outstanding thermal stability, mechanical strength, and chemical resistance in a compact circular form optimized for reproducible testing and device integration. Its resistance to hydrolysis and oxidative degradation makes it valuable in biomedical, chemical processing, and energy applications. Industries use PSU disks in hemodialysis membranes, high-performance filtration systems, and gas separation assemblies. Research focuses on functionalized PSU membranes, electrochemical separators, and gas transport studies, where the disk form provides controlled geometry for standardized experimentation. Applications also extend to proton exchange membranes, ultrafiltration devices, and biomedical implants. With its balance of robustness, processability, and performance in extreme conditions, PSU disks are vital for bridging laboratory research with industrial applications across separation science, healthcare, and sustainable energy systems.
