PPSU recycling and reprocessing problems
문제 현상
Recycling and reuse of expensive PPSU product scrap results in performance degradation.
원인 분석
After multiple passes through the 380°C thermal history, the molecular chains of PPSU degrade and the molecular weight decreases.
해결 방법
Strictly control the regrind ratio ≤20%; supplement with stabilizer.
핵심 요약
PPSU recycling has economic value but requires careful implementation.
