Performance Changes of LCP Medical Applications After Sterilization
Problem Phenomenon
【Problem Phenomenon】Dimensional and strength changes of LCP medical parts after multiple high-temperature steam sterilizations need to be evaluated
Cause Analysis
LCP has good high-temperature resistance and hydrolysis resistance and can withstand steam sterilization, but after multiple cycles, dimensional stability and mechanical retention still need to be verified; medical application regulations require verification data
Solution
Do multiple cycle verification according to the sterilization method and record performance retention; select medical-grade grades and obtain compliance documents; establish sterilization count traceability; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
LCP can withstand steam sterilization; medical applications must do cycle verification and keep records; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
