NOVACHEM purging compounds provide unsurpassed purging performance for all thermoplastic materials in extrusion systems.

For optimal purging performance in dark-to-light color changes and material changes in simple extruders (such as profile or wire coating systems) we suggest that you consider InstaPurge^® Purging Compound, NOVACHEM's best-in-class commodity-grade purging compound.

For the more typical challenging purging applications such as changeovers in large or complex extrusion systems or for control and elimination of gels and carbon we recommend choosing an appropriate product from our SuperNova™ Chemical Purging Compounds.

We urge extrusion operators to read our technical paper, "Toward a Systematic Approach to Evaluation and Resolution of Purging Issues in Thermoplastics Processing", which can be downloaded here.
