PSU (Polysulfone) granules are high-performance thermoplastics with a glass transition temperature of approximately 190°C, making them suitable for high-temperature applications. Their hydrolysis and microbial resistance enable their use in the production of microfiltration and ultrafiltration membranes used in biomedical research and industrial water purification. Polysulfone exhibits high dielectric strength, which supports electrical insulation in aerospace and automotive electronics, ensuring reliability in demanding environments. Additionally, PSU granules are utilized in precision 3D printing for chemically resistant, high-strength laboratory and engineering components used in many research applications.
