FAQs: Stop Carbon Contamination & Black Specks with Asaclean EX Grade

In the plastics processing industry, it's not uncommon for processors to encounter challenges related to carbon contamination and black specks.

This blog post will address some of the most frequently asked questions and concerns about using Asaclean® EX Grade purging compound to combat carbon contamination and black specks. Our goal is to inform and educate, helping you make informed decisions about purging and clearing up any misconceptions. Let's dive in!

1. What Causes Carbon Contamination and Black Specks in Injection Molding, Extrusion, and Blow Molding?

Carbon contamination and black specks occur when small particles of degraded resin, additives, or contaminants accumulate in your injection molding or extrusion equipment's barrel, screw, and hot runner systems. These impurities can lead to poor-quality parts, unsightly surface defects, and increased downtime for maintenance and cleaning.


2.  How Does Asaclean® EX Grade Purging Compound Help Remove Carbon Contamination and Black Specks?

We designed Asaclean® EX Grade purging compound to remove stubborn carbon deposits and black specks from your molding machine or extruder. The compound's high-performance scrubbing action and excellent compatibility with a wide range of resins allow for effective cleaning of your machinery, reducing downtime and improving part quality.

3. Can Asaclean® EX Grade Be Used With All Types of Resins?

Asaclean® EX Grade is compatible with a broad range of resins, making it suitable for most plastics processing applications. However, we always recommend working with an Asaclean® Purging Expert and referring to the product datasheet for specific compatibility information.

4. Can Asaclean® EX Grade be Used for Both Injection Molding and Extrusion?

Yes, Asaclean® EX Grade is suitable for injection molding and extrusion processes. Its versatile formulation allows for the effective cleaning of equipment across a wide range of plastics processing applications.

5.  Are Glass-Filled Purging Compounds Safe for My Machine?

Yes. Asaclean® Purging Compounds are safe for your machine.
After 25 years, Asaclean® has never had a customer contact us about screw or machine damage from using our products.

Some of our competitors share a misconception that mechanical purging compounds are "abrasive." This claim is untrue. Purging compounds reduce machine wear and tear. Asaclean® Purging Compounds prolong the life of your screw and barrel.

We do not recommend EX for hot runners or highly polished screws or dies. Specific grades have gate clearance limitations.  Again, we always recommend working with an Asaclean® Purging Expert and referring to the product datasheet for specific compatibility information.  If you are unsure, ask for help.

6. How Does Asaclean® EX Grade Help Optimize Screw Pulls?

Asaclean's EX Grade tackles carbon contamination and black specks and offers a valuable advantage regarding screw pulls. To demonstrate the efficiency of Asaclean® EX Grade during screw pulls, we have included a 90-second video that you can watch to see it in action. Yes. Asaclean® Purging Compounds make screw pulls much easier, safer, and more cost-effective.

Our EX Grade peels off the screw like a banana peel. It's a revolutionary product that dramatically helps during preventative maintenance and unplanned downtime.

Screw pulls are essential to maintaining and cleaning your injection molding or extrusion equipment. The process involves removing the screw from the machine, which can be time-consuming and challenging without a suitable purging compound. Asaclean's EX Grade simplifies this process, helping to ensure that your equipment stays clean and in optimal condition.

When using Asaclean® EX Grade for screw pulls, you'll notice that it effectively breaks down and removes carbon deposits and other contaminants from the screw. Asaclean® added benefit ensures more thorough cleaning of your equipment, reducing the risk of future contamination and improving the overall efficiency of your production process.
By incorporating Asaclean® EX Grade into your maintenance routine, you'll experience the benefits of a cleaner, more efficient production process.

7. How Does Using Asaclean® EX Grade Benefit My Overall Production Process?

By using Asaclean® EX Grade purging compound to tackle carbon contamination and black specks, plastics processors can experience numerous benefits, including:
a. Reduced downtime for cleaning and maintenance. b. Improved part quality and reduced scrap rates. c. Lower risk of damage to the equipment caused by stubborn carbon deposits. d. Increased overall operational efficiency.
