Melt flow existing from die is unstable and main drive current is fluctuating.
Output decreases without reducing screw speed.
No melt is exiting despite screw is rotating.
Poor mechanical properties.
The chance of degradation in the extruder can be reduced by marking following changes to process:
If degradation occurs by thermo-oxidative mechanism, air should be excluded from the extruder. This can be done by putting a nitrogen blanket on the feed hopper, vent port or at the die depending upon where air is introduced.
If the degradation occurs by chemical reaction with metal surfaces of screw and barrel, a non-corrosive material of construction has to be selected for screw and barrel.
