Influence of cooling rate on PETG transparency
문제 현상
The transparency of products differs significantly under different cooling rates.
원인 분석
The cooling rate affects the molecular chain packing density and free volume, and too fast cooling produces density unevenness.
해결 방법
Control the mold temperature to make the cooling rate uniform; anneal if necessary to homogenize the microstructure.
핵심 요약
PETG transparency is sensitive to cooling conditions.
