PETG '2079851475616104452 poor thermal stability, residence time sensitive
Sorun Belirtisi
When staying at high temperature for a long time, the melt color deepens and viscosity decreases, and product quality deteriorates.
Neden Analizi
PETG has limited thermal stability at high temperature and undergoes thermal degradation during long residence.
Çözüm
Shorten the molding cycle and residence time; lower the rear barrel section temperature; avoid production interruptions; lower the temperature before shutdown.
Temel Çıkarım
PETG thermal stability needs to be maintained in continuous stable production.
