PBT Injection-Molded Parts Absorbing Environmental Moisture During Storage
Fenómeno do problema
The product absorbs moisture from the ambient air when stored under unsealed conditions.
Análise das causas
Although PBT has low hygroscopicity, it still has a certain water absorption rate (0.08%), and moisture accumulates during long-term storage.
Solução
Seal-pack the product; store in a dry environment <40%RH; use moisture-proof packaging materials.
Conclusão principal
PBT storage moisture management cannot be ignored.
