PPS thermal stability is good but processing is not unlimited
Sorun Belirtisi
PPS has good thermal stability (continuous use at 220°C) but this does not mean it can be processed arbitrarily.
Neden Analizi
Long residence time at processing temperature still causes oxidative degradation.
Çözüm
Strictly control barrel time; during production reduction keep equipment at holding temperature rather than production temperature.
Temel Çıkarım
PPS has good thermal stability but this does not mean processing has no limits.
