TPE vs Silicone Comparison
Problem Phenomenon
Insufficient temperature resistance after replacing silicone products with TPE
Cause Analysis
Silicone has better temperature resistance and biocompatibility than TPE; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry information and should be confirmed first during troubleshooting
Solution
Silicone for high temperature and implantable medical use; TPE for general elastic parts; select material by requirements; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
TPE and silicone are divided by temperature resistance and medical grade; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
