PurgeClean is a family of industrial purge compounds developed to address different plastic processing needs and cleaning challenges. Start by identifying the problem, processing conditions, requirements, or results you want to achieve. We can then help you identify the PurgeClean product that best matches your specific application.
1. Identify Your Processing Situation/Problem
Routine Maintenance, Color change • Resin change • Carbon • Black specks • Shutdown • Hot runner • Film extrusion
2. Match Your Processing Conditions

3. Select the Right PurgeClean Solution
What Is a Purge Compound?
A purge compound is a specialized material used to clean plastic processing equipment by removing residual resin, color, deposits, and contaminants from the machine between production runs, material changes, maintenance, shutdowns, and startups.
Purge compounds are used in injection molding machines, extruders, blow molding equipment, hot runner systems, and film extrusion lines. The right purge compound can help processors achieve cleaner material transitions, reduce production interruptions, minimize waste, and maintain more consistent processing performance.
For many plastic processors, purging is more than simply cleaning a machine. It is an important part of production efficiency, quality control, and equipment maintenance.
