Purging Compounds Add to “Green” Manufacturing
For plastics manufacturers, the three most common and costly forms of waste are scrap resin, lost time, and wasted energy. Hence, using an effective purging compound solution will reduce all of these sources of waste and lost profits. When performed haphazardly, purging any machine can be financially and environmentally expensive.
Using straight resin to remove the unwanted material from the barrel requires a large amount of time, resin, and energy to properly clean out the machine. Therefore, using an effective commercial purging compound like those offered by Slide Products can reduce waste in all of these areas. Sure, a purging compound costs more per pound when compared to straight resin. But the secondary costs of scrap, energy, and time associated with using straight resin more than exceed the costs of an effective purging compound. And with less scrap resin headed for the landfill, the environmental advantages of using a commercial-grade purging compound are obvious as well.
Slide offers two different purging compound options. The popular and easy-to-use PDQ is a water-based purging additive. It is simply mixed with a carrier resin to create a mixture that quickly and inexpensively removes the unwanted old resin from the machine; thus minimizing lost resin, time, and energy. Slide’s heavy-duty purging compound is the NPT. This ready-to-use formulation is simply added directly to the machine with no extra resin needing to be added. NPT works by chemically destabilizing the unwanted polymer, effectively liquefying the material so that it can more easily be flushed out of the barrel. And again, the use of NPT greatly speeds up the purging process and eliminates much of the wasted resin, energy, and time.
A training video on Slide’s purging compounds is available on our web site. Show this video to your purge prospects. And remember to promote our purge products as a solution to increase the “Green” aspects of a manufacturing process. A good purging compound improves a company’s “Green” position in both the environmental and profitability realms.
