Purging Concentrates

OnCap™ Multi-Purge™ Additives

Reduce Clean-out Time, Increase Efficiency

Our purge concentrates are a cost-effective and universal way to help increase the effective manufacturing time of your plastics processing machinery. OnCap™ Multi-Purge™ formulations are cost-effective because they significantly reduce clean-out time during color and material changes. Multi-Purge solutions are available for a variety of processing conditions and operating temperatures, and can be recycled.

The effectiveness of Multi-Purge concentrates comes from the mechanical scrubbing action during purging between the material, plasticizing screw and barrel. This dynamic action loosens and removes degraded material and color specks from barrel walls, screw flights, and pitted or cracked areas of your equipment, leaving it ready for the next run.
