PSU (Polysulfone)
Trusted Wherever Heat, Steam, and Precision Come Together
Industrial components are often expected to perform in environments where hot water, steam, and continuous mechanical stress are part of everyday operation. In these situations, material failure is not an option. Polysulfone (PSU) has become a proven engineering solution because it maintains its strength, rigidity, and dimensional accuracy even after prolonged exposure to demanding conditions.
Its transparent amber appearance, combined with excellent hydrolytic stability, mechanical durability, and electrical insulation, makes PSU a preferred material for applications in medical technology, laboratory equipment, electronics, water treatment, and industrial machinery.
