Summary
If you’re running pounds of resin through the barrel and mold until it comes out clean, this wasteful process will cost you time and create decreased profit margins. The right purging compound will turn much of that unwelcome expense back into output. Slide’s purging compounds speed up resin-to-resin and color-to-color changes, maximizing your productivity and decreasing the costs.

Product Description
There are typically two (2) types of purging compounds:
1) Mechanical
2) Chemical
Mechanical
A mechanical purging compound is effective for numerous applications. As the name suggests, mechanical purging relies on shear force and the differences in viscosity to clean molds. There is no chemical reaction and no soak time needed to purge the molding machine.
Chemical
A mechanical purge may not be effective in sections of the barrel, screw, or manifolds where there is low pressure. In such cases, a chemical purge is the best choice for cleaning. Instead of shear force, a chemical reaction takes place when the purge contacts the resin or carbon. Some chemical purging agents require no soak time while others require up to 30 minutes; this soak time depends on several factors, such as the resin, size of barrel and screw, manifold size, etc.
Our experts can help you
Choosing the right purging compound for your applications requires a little research and testing. Slide offers both mechanical and chemical purges, as well as a unique liquid purging compound with advantages of both mechanical and chemical purges.
A few of Slide’s best-selling purging compounds include:
- Econo-Purge Purging Compound: A mechanical, low-odor, and GRAS rated compound excellent for use through hot runner systems and safe to purge through the mold. This powerful purging compound helps to remove old resin and color residue in extrusion, injection, and blow molding operations.
- KLENZ Purging Compound: A chemical and mechanical combination polyolefin resin carrier safe for high-temperature molds exceeding 330°F. This chemically reactive compound is safe to purge through the mold and helps to eliminate color streaking and black specks.
- PDQ Liquid Purging Compound: A highly effective mechanical/chemical hybrid, this is a concentrated liquid purging compound that can be mixed with any carrier resin to remove residue.
