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