Metal-Catalyzed Degradation of PBT
Problembeschreibung
PBT degrades faster in environments containing metal catalysts such as copper and iron.
Ursachenanalyse
Certain metals (copper, iron) and their ions catalyze the oxidative degradation of PBT, and contact accelerates aging.
Lösung
Avoid direct contact between PBT and catalytic metals such as copper; use stabilizers and metal deactivators.
Wichtigste Erkenntnis
PBT metal-catalyzed degradation is a factor to note when selecting materials.
