E/Z Purge®

[tab name=Description]

 

E/Z Purge® is an ammonia-free, water-based product that removes and cleans unwanted color, material or burned polymer from extruders, injection or blow molding equipment. Purging is a critical part of routine maintenance but costly in terms of system downtime, wasted materials and labor costs. The efficient action of cleaning and purging with E/Z Purge® enables you to make quick, complete changeovers from one color to another and from one resin type to another using your own scrap resin. E/Z Purge® is safe for workers and the environment.

E/Z Purge® provides unsurpassed purging performance of thermoplastic materials and residues allowing speedy color and material changeovers with scrap generation minimized. It was developed as a quick, cost-saving method for cleaning injection and blow molding machines as well as film and sheet extruders. Down time is reduced because there is no need to strip down and manually clean deposits from melt passages. E/Z Purge® easily mixes with your own scrap resin to produce unsurpassed purging performance, eliminating the need to purchase more costly resin pellets for purging.

[tab name=Directions for Use]

1.    Fill a plastic container with double the amount of resin needed to fill the extruder barrel, or the amount usually used, if less.

2.     Pour E/Z Purge® into the resin, mixing thoroughly using non-absorbent gloves, at approximately 2% of E/Z Purge® by weight. Example: 12 lbs. of resin = 4 oz. of E/Z Purge®; 50 lbs. of resin = 1 lb. of E/Z Purge®. Simply multiply your pounds of resin by .02 and that will indicate the amount of E/Z Purge® to use.

3.     Set the zone temperatures of your machine slightly lower than normal operating temperature.   

4.     INJECTION AND BLOW MOLDING: Feed the E/Z Purge® resin mix into the hopper very slowly with the extruder set at 10 to 15 RPM. Continue feeding the purge mix until you see the material coming out of the die. When the material comes out from the die, stop the screw for several minutes to let the E/Z Purge® work. Start up again and feed the next resin into the machine.

5.     FILM AND SHEET EXTRUDERS: Use the same procedure above but wait 10 to 15 minutes before starting up again.

6.    Before feeding new resin into hopper, be sure that all moisture is removed and screw is stopped while drying.

7.    For very dirty machines or severely burned on material, the above procedures may need to be repeated.

8.    Using E/Z Purge® in a weekly preventive maintenance program can eliminate polymer buildup on machine parts.
