Yellowing of Natural-Color PBT Products During Storage
문제 현상
White or natural-color PBT products turn yellow after being stored in the warehouse for several months.
원인 분석
The antioxidants in PBT are gradually consumed, and oxygen and ultraviolet rays in the air slowly oxidize it, causing yellowing; high storage temperature accelerates this.
해결 방법
Use a high-efficiency antioxidant formulation; store sealed away from light; control the storage temperature <30°C.
핵심 요약
PBT yellowing during storage is the result of slow oxidation.
