PESU Electrical High-Temperature Application
Problembeschreibung
【Problem Phenomenon】Material selection for high-temperature electrical insulation parts, conventional engineering plastics' dielectric properties decay with temperature
Ursachenanalyse
PESU has stable dielectric properties at 200℃, high volume resistivity, and belongs to Class H (180℃) insulation materials; suitable for high-temperature electronic components and switch parts
Lösung
Select PESU for high-temperature electrical parts according to Class H insulation; verify dielectric properties by actual measurement at working temperature; retest dielectric after long-term thermal aging; after adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Wichtigste Erkenntnis
PESU is a Class H insulating transparent material, endorsed by dielectric stability at 200℃; after confirming effectiveness, fix 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
