Extrusion & Post

EEA extruded film has gel particles
Sorun Belirtisi
Transparent gel particles of 0.1-0.5mm appearing on the EEA extruded film surface
Neden Analizi
High molecular weight components in EEA not fully melted during extrusion forming local high crystallization zones; extrusion temperature too low or insufficient mixing
Çözüm
1) Increase extrusion temperature by 5-10°C to ensure full melting; 2) Increase screw mixing section length; 3) Inspect raw material to ensure consistent grade; 4) Replace with a finer 120-mesh screen to intercept unmelted particles
Temel Çıkarım
Gel particles are caused by insufficient melting; increasing temperature and mixing is the key
