TPE Color Masterbatch Carrier
Fenómeno do problema
TPE products have color specks and sticky surfaces
Análise das causas
Poor compatibility between the color masterbatch carrier and TPE, precipitating on the surface; 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
Solução
Select TPE-specific color masterbatch (SEBS or EVA carrier); control the addition ratio; 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
Conclusão principal
TPE color masterbatch requires a dedicated carrier; 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
