TPE stress cracking
Fenómeno del problema
TPE products crack after contacting chemicals
Análisis de la causa
Certain chemicals attack TPE; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
Solución
Confirm medium compatibility; select chemical-resistant grades; avoid contact with aggressive media; 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, so as to locate effective measures
Conclusión clave
Verify compatibility first before chemical contact; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
