Fenómeno del problema
PBT products break and fail in the drop test.
Análisis de la causa
The impact strength is insufficient (especially at low temperatures); the product has stress concentration and notches; the internal stress is large.
Solución
Use a toughened PBT grade; optimize the design to eliminate stress concentration; fully anneal.
Conclusión clave
PBT drop performance is closely related to toughness and design.
