PPSU recycling and reprocessing problems
Fenómeno del problema
Recycling and reuse of expensive PPSU product scrap results in performance degradation.
Análisis de la causa
After multiple passes through the 380°C thermal history, the molecular chains of PPSU degrade and the molecular weight decreases.
Solución
Strictly control the regrind ratio ≤20%; supplement with stabilizer.
Conclusión clave
PPSU recycling has economic value but requires careful implementation.
