PPSU medical sterilization
Problem Phenomenon
PPSU medical repeated steam sterilization; performance retention and color stability.
Cause Analysis
PPSU steam sterilization resistance; repeated cycles over 1000 times; performance retention; color stability; medical compliance; hydrolysis stability.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Sterilization method verification; ②cycle testing; ③performance tracking; ④color management; ⑤compliance documents.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPSU medical sterilization's thousand-cycle-level tolerance is an advantage; verification ensures reliability; compliance ensures market access.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
