PPSU decomposition from excessive processing temperature
Sorun Belirtisi
PPSU products darken in color, foam, and degrade in performance.
Neden Analizi
Processing temperature >390°C exceeds PPSU thermal decomposition temperature; foaming and degradation products cause deterioration of appearance and performance.
Çözüm
Strictly control barrel at 340-380°C, never exceeding 390°C; shorten residence time.
Temel Çıkarım
PPSU ultra-high temperature processing window is narrow and needs fine management.
