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