Why Asaclean® Purging Compounds are the Best Choice for Medical & Pharmaceutical Processors

Asaclean® has safe, effective, and reliable high-performance purging compounds designed for the specific needs of medical manufacturers. Whether you’re molding super-engineering resins for medical parts, extruding clear tube for oxygen masks, making blister packs for syringes or molding pill bottles and caps for prescriptions, we’ve helped people just like you quickly remove contamination and achieve dramatic cost savings.

When we hear from processors in the medical industry, they usually are asking for help with a handful of different processing issues. If you’re reading this section, then you’ve probably experienced some of these struggles firsthand:

  • You’re dealing with black specks or contamination.
  • Your teardowns are time-consuming and hurt your productivity.
  • You’re running clear parts need to eliminate haze and residue issues.
  • You work with super-engineering resins and have difficulty with changeovers.
  • You need specialized, reliable products that you can depend on.
  • You’re not sure if purging compounds work in your application

Medical supplies

Medical and pharmaceutical processors have the industry’s tightest quality specifications and run difficult resins including PVC, TPU, ABS, HDPE, PC, POM, PMMA, PEEK, etc. Scrap is incredibly costly when you’re running expensive resins. Also, you know you need a spotless machine to run acceptable product. Contamination issues and frequent screw pulls further reduce your productivity.

As a medical plastics manufacturer, you likely rely on high-volume output to surpass budgeted profit margins. As one example, special, thin-walled molds for medical plastics parts offer the advantage of high-volume product runs with short cycle times – a necessity since these applications run multiple colors.

However, numerous resin transitions, from thin-walled molding, in particular, result in high scrap rates and production downtime that decimate your profit potential.

Many medical processors assume that these headaches are an inevitable part of the job.

We have good news. It doesn’t have to be that way.


On average, Asaclean®’s medical customers save 59% on reduced scrap & downtime.

4 Easy Ways for Medical Processors to Improve Productivity

staff testing out medical supplies

1. Avoid Cross-Contamination: Purge Preventatively & Don’t Run Until Failure

Purge regularly to make sure you’re keeping your screw and barrel clean. A personalized Purge Program can help you avoid most contamination issues from occurring. The best offense is a good defense.

If you’re making external medical products, this could be a fast and easy way to avoid tear downs.

EX Grade is an unbelievable product for pulling screws for our maintenance department.  It helps us get back up and running in a matter of minutes.”
Vincent Zirkle , Plant Manager, Blue Ridge Molding, North Carolina

Asaclean® customers save up to 92% on screw pulls.

2. If Tear downs are Essential, Use EX Grade Purging Compound for Quick & Easy Screw Pulls

Some applications cannot risk any level of contamination and necessitate a manual screw pull. Removing your screw from your machine without a purge requires great effort, and the cleaning itself takes hours of manual, tedious scrubbing. You must remove the layers of resins or contaminants that have accumulated around the screw. This excessive downtime is certainly affecting your company’s bottom line.  If you’re running until failure or running until you experience severe contamination, EX Grade is a solution that can make your life much easier in a hurry.

3. Use a Specialized Asaclean® Purging Compound Formulated for Your Needs

In addition to EX, there are incredible specialized Asaclean® products designed for any processing situations you might face. We offer grades designed for clear applications, low-temp resins, super-engineering resins, extrusion, etc. Take a few moments to work with an Asaclean® Purging Expert to find the right product for your needs.

4. Seal Your Machine with Purge During Shutdowns

It’s amazing how many production teams forget to seal with Asaclean® before weekend and holiday shutdowns. Purging compounds do not oxidize in the barrel and have a material affinity that removes carbon and any lingering contamination at start-up. Sealing with Asaclean® may be one of the biggest time-saving decisions your production team can make.
