Testimonials - Extrusion Coating

Eric B. is the Coating Department Lead Foreman at a coated products company in New England. He tells us how SuperNova LT Chemical Purging Compound enhanced his company's productivity and profitability:

We coat web product with either EAA or LDPE and we have to go back and forth between them a couple times a week. When we used to just flush with the next resin it'd take us a couple hours. We improved on that by using a purging compound - got it down to about an hour and a half. But we still had an issue.

The purge got the old resin out in about 30 minutes, but then we had to run scrap for about 45 minutes to an hour 'til all of the purge was out of the system. We'd keep dragging white specks in the coating for that long. That stuff just gets ground up and sent to the landfill, so it was pretty expensive.

NOVACHEM came up with the SuperNova LT product for us to try. We found it
worked just as well as the other stuff for getting the previous resin out, but
then the follow-on resin cleaned out the SuperNova in 5 or 10 minutes. So we
cut our scrap way down. And it works just as well in either direction - out of the
EAA or out of the PE.

We're saving about four hours a week compared to the other product, and the scrap is down by 400 pounds a week. That's product we can sell, now!

Just as a side benefit, the other product smelled really strongly of ammonia. Sometimes the guys on the floor were really irritated by it. The SuperNova material hasn't got any of that so the operators like it a lot better.

Y'know, the other funny thing is that the SuperNova LT actually costs a little less than the other product we were using. But it's worth a lot more to us.
