Key Signs You’re Using the Wrong Purging Compound

In plastic processing, time is money—and waste is the enemy. If your Purging Compound isn’t delivering fast, clean results, it could be doing more harm than good. How do you know if your current purge is falling short? Watch for these warning signs:

Black Specks Keep Appearing

Stubborn black specks or carbon residue aren’t just annoying—they signal contamination. An Effective Purging Compound removes carbon deposits completely, preventing rework, product defects, and reputational damage.

Color Changeovers Are Messy

Switching from red to white shouldn’t leave streaks or a pink tint. Smearing, streaking, or color bleeding indicates your purge isn’t cleaning thoroughly. The right solution clears old material completely, leaving a neutral base for the next batch.

Manual Screw Cleaning Is Still Pulling

If you’re dismantling screws to clean them manually, your purge isn’t doing its job. Modern, high-performance compounds reach deep areas like screw flights, barrels, and hot runners—without disassembly—saving labor and downtime.

Excess Resin Usage

Flushing lines with base resin doesn’t clean—it dilutes contaminants and wastes material. Specialized purging solutions bond with residue and remove it efficiently, protecting product quality and your bottom line.

Inconsistent Results

If results vary from batch to batch, your purge isn’t stable. A reliable compound delivers consistent performance across temperatures, polymers, and production lines.

Frequent Downtime

Regular stops for cleaning or difficulty restarting after maintenance may indicate purge issues. Advanced Purging Compounds reduce downtime, enabling faster startups, smoother changeovers, and higher productivity.

Your Compound Isn’t Process-Specific

Not all purges are suitable for every process. Blow molding, extrusion, and injection molding each require tailored solutions. Using a general-purpose compound often increases cleaning time. UNICLEANPLUS™ offers customized solutions designed for your specific process.
