TPE Medical Application
Fenómeno del problema
TPE medical parts require biocompatibility, but performance declines after sterilization, or they become sticky
Análisis de la causa
Medical-grade TPE requires biocompatibility certification; high-temperature steam sterilization softens and deforms TPE; irradiation and EO sterilization are applicable; stickiness risk requires formulation control; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Choose certified grades for medical-grade TPE; ②Select the sterilization method by material compatibility; ③Formulation management of stickiness risk; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
TPE medical application is a dual threshold of certification and sterilization; biocompatibility plus sterilization compatibility, neither can be omitted; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
