Control of viscosity abnormality in PEOX blown film medical products
Problem Phenomenon
During PEOX blown film production of medical products, the problem of uneven viscosity occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +70-90°C, moisture content >0.3% exceeding the standard, and insufficient cooling.
Solution
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and strengthen cooling.
Key Takeaway
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
