Purgex is the answer for all of your commercial purging needs. We offer purging compounds engineered to handle any application. Whether your molding operation uses unfilled commodity resins or viscous engineering resins, we have a purging compound designed to cost effectively meet your needs.
All Purgex blends are safe for hot runner systems. Our product effectively cleans injection molding gates as small as .030-inch, or .75mm.
Purgex has been proven to be highly effective in speeding changes of color and material within the molding process. Purgex is also the only compound on the market that neutralizes acid gases produced by PVC. With Purgex there is no resin interaction, and because it acts as a neutralizer, PVC and acetal resins can be safely processed in sequence, on using the same equipment.
Purgex works effectively in all of these molding applications:
- Injection Molding - Purgex is safe for hot runners, with gates as small as .030-inch, or .75mm.
- Extrusion - Purgex can be processed through dies with gaps as small as .030-inch, or .75mm.
- Blow Molding - Purgex provides effective color changes in screws, barrels, dies, and accumulator heads.
