Preparation Before Purging

1. Keep temperature settings constant.
2. Maintain resin flow rate.

Purging The Machine

1. Stop resin feed.
2. Empty machine.
3. Remove screen pack (recommended but optional).
4. Add Purgex to the machine.
   Rule of Thumb: Use 15 lbs of Purgex per 100 lbs of throughput. Note that after Purgex is used on a regular basis, the amount of Purgex used to purge can be reduced by 25 to 50%.
5. When Purgex begins to exit the die, stop screw rotation.
   Optional: Soak Purgex in the machine for 5 to 15 minutes for first time purging or heavily contaminated lines.
6. Follow with next resin to rinse out Purgex (for about 5 minutes).
7. When resin appears clean and smooth, install screen pack (if removed in step 3).
8. Begin production.

Processing Tips:

• Maintain as close to production speed as possible when purging.
• When restarting the screw, monitor pressure and amp meters as screw speed is increased to standard operating speed.
