PBT Products Breaking in the Drop Test
Problem Phenomenon
PBT products break and fail in the drop test.
Cause Analysis
The impact strength is insufficient (especially at low temperatures); the product has stress concentration and notches; the internal stress is large.
Solution
Use a toughened PBT grade; optimize the design to eliminate stress concentration; fully anneal.
Key Takeaway
PBT drop performance is closely related to toughness and design.
