Q

Air Streak Bubbles (air streaks) in Slot Die Coating

A

The three major causes of extrusion bubbles (raw material moisture, thermal decomposition gas generation, screw air entrainment) need to be treated differently: moisture type—fully dry to the specified moisture content; decomposition type—lower the processing temperature to avoid degradation; air...
