CEF extrusion film has gel spots
문제 현상
The CEF extruded film has transparent gel spots of 0.2-1mm
원인 분석
CEF residual crosslinked gel; the processing temperature is too high and local crosslinking occurs
해결 방법
1) Low gel content CEF; 2) Processing ≤220°C to avoid thermal crosslinking; 3) Screen 80-120 mesh interception
핵심 요약
CEF gel spots are caused by residual crosslinking; raw material control and filtration are the key
