Metal-Catalyzed Degradation of PBT
문제 현상
PBT degrades faster in environments containing metal catalysts such as copper and iron.
원인 분석
Certain metals (copper, iron) and their ions catalyze the oxidative degradation of PBT, and contact accelerates aging.
해결 방법
Avoid direct contact between PBT and catalytic metals such as copper; use stabilizers and metal deactivators.
핵심 요약
PBT metal-catalyzed degradation is a factor to note when selecting materials.
