Neutrex will discuss the latest in Purgex purging compounds, which speed up color changes, eliminate contamination, reduce rejects and decrease downtime. The compounds are engineered to efficiently clean the barrel, screw, check ring, nozzle and hot runner systems in injection molding equipment and to effectively clean extrusion, blowmolding, and film and sheet equipment. 

Neutrex performs on-site R&D lab testing and in-plant trials on every specialized product in its line of commercial purging compounds. Purgex grades are comprised of active ingredients with a resin carrier and are engineered to clean thoroughly and quickly to maximize color/resin change turnaround and reduce scrap. Most grades are designed for versatility and are effective on a broad range of resins and multiple production methods for applications ranging from large automotive instrument panels to small medical components.
