EAA surface snakeskin texture
문제 현상
Snakeskin-like irregular texture on the surface of EAA extruded products
원인 분석
Extrusion temperature too low, uneven melt elastic recovery; uneven die temperature distribution
해결 방법
1) Increase extrusion temperature to the processing temperature range; 2) Homogenize die temperature to ±2°C; 3) Reduce extrusion rate to reduce elastic recovery
핵심 요약
Snakeskin texture is caused by low-temperature extrusion and elastic recovery; raising temperature and reducing speed is key
