PSU
Polysulfone is a transparent amber engineering plastic used for heat-resistant parts that may require repeated steam sterilization.
Define the service and cleaning conditions together
For a PSU component, discuss the operating temperature, cleaning conditions and any repeated sterilization requirement with Aria. We help you review the grade and geometry against those conditions. Any required compliance documentation or acceptance test must be stated for the particular part, not inferred from the polymer name.

Compatible manufacturing processes
Selection requirements
- CNC Milling Services · Injection molding · Precision CNC machining · CNC turning
Injection molding, CNC milling and turning, extrusion and thermoforming. Dry thoroughly; the supplied processing reference is at least 150°C. Qualify adhesives and cleaning agents to prevent stress cracking. Confirm drying, outdoor stabilization and the applicable ASTM or ISO test method.
Advantages and considerations
Advantages
Good hydrolysis resistance, stiffness and dimensional stability; useful electrical and radiation performance. Supplied references give continuous service around 149°C.
Material limitations
Ketones, chlorinated and aromatic solvents can cause attack or stress cracking. Unmodified grades need UV protection outdoors.
