Translucent/Hazy PBT Injection-Molded Parts (Non-Transparent Grade)
문제 현상
Partially translucent or hazy areas appear in natural-color non-transparent PBT products.
원인 분석
The local area is not fully crystallized (rapid cooling causes incomplete crystallization), and the optical properties of this area are different from those of the fully crystallized area.
해결 방법
Increase the mold temperature to ensure uniform crystallization; extend the cooling time; anneal the product to homogenize crystallization.
핵심 요약
PBT haziness is the optical manifestation of uneven crystallization.
