POE extrusion film gel particles
Problem Phenomenon
POE extruded film surface shows 0.1-0.5mm transparent gel particles
Cause Analysis
High molecular weight components in POE not fully melted during extrusion form local high-crystallinity regions; extrusion temperature too low or mixing insufficient
Solution
1) Raise extrusion temperature 5-10°C to ensure full melting; 2) Increase screw mixing section length; 3) Raw material inspection to ensure consistent grade; 4) Change to finer screen 120 mesh to intercept unmelted particles
Key Takeaway
Gel particles are caused by insufficient melting; raising temperature and mixing are key
