Polysulfone (PSU) plastic is a high-performance, amorphous thermoplastic known for its exceptional thermal stability, mechanical strength, and chemical resistance. As a transparent engineering material, PSU polymer is widely used in medical devices, fluid handling systems, electrical components, and industrial applications that require reliable performance under extreme conditions.
Whether you're sourcing custom PSU components, medical-grade polysulfone parts, or transparent PSU sheets, we offer tailored solutions backed by years of expertise and precision manufacturing capabilities.
Our PSU thermoplastic maintains structural integrity at temperatures up to 160°C, making it ideal for autoclavable medical devices, sterilizable labware, and hot fluid handling applications.
Polysulfone resists a wide range of acids, bases, and cleaning agents, ensuring long-term durability in aggressive environments such as chemical processing and water treatment systems.
Unlike many other high-performance polymers, PSU polymer offers optical clarity, making it suitable for sight glasses, filter housings, and components where visibility matters.
We supply medical-grade PSU and FDA-compliant polysulfone plastic, offering safe, biocompatible options for healthcare and food processing industries.
