PC/ABS high and low temperature impact
Problembeschreibung
The impact strength of PC/ABS decreases at -30°C low temperature.
Ursachenanalyse
The Tg of the rubber phase in ABS is about -80°C and the secondary transition of PC is at -100°C, both having good low-temperature toughness, but improper ratio and severe PC degradation cause low-temperature embrittlement.
Lösung
Ensure the PC component is not degraded; toughening formulation design; low-temperature verification testing.
Wichtigste Erkenntnis
PC/ABS low-temperature impact requires comprehensive consideration.
