Control of appearance abnormality in PEOX extrusion pharmaceutical films
Problem Phenomenon
During PEOX extrusion production of pharmaceutical films, the problem of not up to standard appearance occurs.
Cause Analysis
Mainly due to the processing temperature deviating from the window +60-100°C, moisture content >0.3% exceeding the standard, and excessively long residence time.
Solution
Strictly control the temperature within the recommended range, fully dry the material to moisture content <0.1%, and reduce the screw speed.
Key Takeaway
PEOX processing requires precise control of the three elements of temperature, humidity, and residence time.
