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