Purgex™ FDA approved purging compounds are a group of top quality, high value, competitively priced commercial purging compounds. Purgex has been used worldwide on injection molding, extrusion, and blow molding applications.
These products have mechanical activity for effective cleaning plus foaming action for enhanced mixing and a lubricant for easy removal from the machine.
Purgex grades are composed 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, like GRAs purging compounds, are designed for versatility and are effective on a broad range of resins and multiple production methods.
Specialty Purgex grades are available for specific resins and processes such as:
|Polypropylene copolymer||Blown Film|
