PPSU: Sulfone Selection and Cleaning Cycles

PPSU is polyphenylsulfone, a different polymer from PPS and PSU. Material reference.

Sulfone Selection and Cleaning Cycles

For a reusable component, base the comparison on the actual cleaning or sterilization process, load and required life. A family-level statement about heat resistance does not qualify a finished part for a medical use or guarantee performance through an unspecified number of cycles.

Manufacturing and acceptance checks

Request the exact grade, colour and stock or moulding route. Define the cycle, chemicals, temperature and dimensional or mechanical pass criteria. Obtain application-specific evidence where required and evaluate representative finished parts after the specified exposure rather than only in the as-made condition.
