Metal-Catalyzed Degradation of PBT
Fenómeno do problema
PBT degrades faster in environments containing metal catalysts such as copper and iron.
Análise das causas
Certain metals (copper, iron) and their ions catalyze the oxidative degradation of PBT, and contact accelerates aging.
Solução
Avoid direct contact between PBT and catalytic metals such as copper; use stabilizers and metal deactivators.
Conclusão principal
PBT metal-catalyzed degradation is a factor to note when selecting materials.
