Aging of PBT products in automobile engine compartments
Sorun Belirtisi
PBT parts age and fail rapidly in the engine compartment (high temperature + oil + vibration) environment.
Neden Analizi
High temperature (>120°C) + engine oil + vibration multi-factor coupling accelerates degradation and fatigue, and the antioxidant is consumed and exhausted.
Çözüm
Select PBT grades with high-temperature-resistant antioxidant systems; consider stress relaxation and creep in product design; conduct engine compartment environment simulation tests.
Temel Çıkarım
PBT applications in automobile engine compartments require targeted formulation design.
