Improved purging agent promises no residue at lower purging cost

It's a big promise but the supplier says it has customers' firsthand experience to back it up. This new and improved purging agent combines non-melting but softening thermoplastic scrubbing granules with an expanding proprietary additive. This combination removes color and contamination without leaving behind residue due to the combined power of the thermoplastic's scrubbing action and the expansion of the additive.

Dyna-Purge new K
It scrubs, it expands, and soon all of the residue is gone. Dyna-Purge's K purging compound will be officially introduced at the K show.
The purging compound is called Dyna-Purge K and is supplied by the Dyna-Purge Division of Shuman Plastics Inc (Depew, NY). Nancy Mitchell, the supplier's technical product manager, explains, "Dyna-Purge K expands even more than previous formulations to clean hard to reach areas on the first purge. It cleans faster and reduces scrap and reject rates, while only a small amount of the compound is required."

The company reports that processors who have switched from the established K grade to the improved one have seen savings up to 15%. Dyna-Purge K is to be used for purging low-temperature thermoplastics ranging from 143°C to 287°C (290°F to 550°F); this would include PP, PE, EVA, TPO, and TPE. 

The official tradeshow launch of the improved Dyna-Purge K agent will be made, coincidentally, at the K 2010 tradeshow, which begins next month. Company officials will be keen to discuss the new purging agent, and customers' experience with it, at the company's K show booth, Stand 13/B91-21.
