PPSU decomposition from excessive processing temperature
문제 현상
PPSU products darken in color, foam, and degrade in performance.
원인 분석
Processing temperature >390°C exceeds PPSU thermal decomposition temperature; foaming and degradation products cause deterioration of appearance and performance.
해결 방법
Strictly control barrel at 340-380°C, never exceeding 390°C; shorten residence time.
핵심 요약
PPSU ultra-high temperature processing window is narrow and needs fine management.
