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