What Is a Purging Compound?

A purging compound is a specially formulated material used in the thermoplastics industry to clean screws, barrels, nozzles, dies, and hot runners in injection molding machines and extruders. Unlike traditional virgin resin cleaning, this cleaning agent significantly reduces machine downtime and scrap generation during material or color changes.

Why Use a Purging Compound for Plastic?

Using a purging material designed for plastics ensures faster and more effective cleaning. These compounds are formulated with agents such as emulsifiers, foaming elements, and mild abrasives that help remove contamination from machinery. Unlike molding-grade resins, which aren’t meant for cleaning, these materials are specifically developed for system flushing.

Key Benefits of Using Purging Compounds:

  • Reduces Scrap: Effectively clears residue and leftover color from previous production runs, minimizing waste.

  • Minimizes Downtime: Helps speed up resin and color changeovers, saving valuable production time.

  • Removes Contaminants: Breaks down carbon deposits, gels, and streaks, reducing part rejection and avoiding unexpected production halts.

  • Prevents Screw Pulls: Regular cleaning reduces the need for manual screw removal and internal cleaning.

  • Cleans Hot Runners: Specially formulated unfilled compounds are safe for use through molds and effective for cleaning stubborn color residues in hot runners.

  • Lowers Rejection Rates: Proper cleaning after material changes or shutdowns results in consistent quality and fewer rejected parts.

  • Cost-Efficient: While evaluating the investment, consider not only the price of the compound but also savings in labor, material waste, machine time, and customer satisfaction.


Types of Purging Compounds

There are several types of purging materials available to meet different manufacturing needs:

1. Mechanical Purging Compounds

These rely on physical force to remove contaminants and are typically pellet-based. They combine base resins with low melt flow indices and additives for effective scrubbing.

2. Liquid Purging Compounds

These chemically active liquids induce flow instability and penetrate hard-to-reach zones inside the barrel. They’re highly concentrated and used in small quantities for efficient contamination removal.

3. Chemical Purging Compounds

Designed for deep cleaning, these require a short soak period (5 to 30 minutes) and operate through internal chemical reactions. They are available in various grades and are among the more premium options.
