To keep the material dry, use of hopper dryer is recommended (95 -
105°C).
To prevent decomposition of material, follow the recommended conditions
below. |

| • |
In case of decomposition of
the material or any fear of decomposition, reduce the cylinder temperature
and purge (discharge) the material from the cylinder. During purging,wear
safety goggles and keep hands and face away from the nozzle section. |
