Are changeover times steadily increasing? Are you having difficulty starting up Monday mornings? Are you experiencing high reject rates due to contamination? These are almost universal issues effecting plastics processors, regardless of process or product. Using a Commercial Purging Compound (CPC) can address these issues, as well as increase efficiencies, improve labor utilization, and improve customer response times. And, maybe you can even lower inventory for those just-in-time jobs because you are able to quickly change colors or resins, reducing necessary safety stock levels.
But what if you are already using a CPC, and are seeing the aforementioned issues? You make sure your operators are following purging instructions to the letter, you ask your CPC supplier if there have been any issues with your lot number. You check materials, heater bands, you pull screws and tear apart dies…but, everything checks out. But, did you consider whether you are using the correct purging compound for your specific application?
The two main types of purging compounds on the market are mechanical and chemical. However, knowing the differences is not enough to make sure you have selected the CPC that will help you put your best foot forward. There is far more to consider: what is the carrier resin; do you need a glass-filled grade; is material affinity working in your favor; do you have complex downstream equipment; are you purging a hot runner; are there dead spots or low flow areas in your process; etc.
There is no one-size-fits-all when it comes to Commercial Purging Compounds. This webinar will not only cover the basics of purging, but will supply criteria to help you select the correct purge, while also offering tips to help you improve your purging efficiency.

Eric: Thanks, Trey. Good morning, everyone. So we will discuss “How to Choose the Proper Purging Compound For Your Application Today.” As Trey mentioned, I come from Sun Plastech. We are the sole distributor and sales arm of Asahi Kasei for ASACLEAN Purging Compounds in North and South America as well as Australia.
Asahi Kasei is a global company located, stationed in Tokyo, Japan. Asahi owns many different types of companies including building materials, healthcare and performance plastics. I am part of Sun Plastech as part of the performance plastics division as well as Asahi Plastic North America, also known as APNA located in Fowlerville, Michigan, their sister company, and they manufacture many of our ASACLEAN Purging Compounds here in the U.S. So with that, I will begin.
So what are we looking to do here? With purging compounds, we want to use purging compounds to gain a competitive edge, of course. You know, we want to be able to produce more parts per hour, we want to lower production costs, and we want to reduce machine time. So there goes three key areas. That’s how you’re going to gain an edge against your competition, much of your competition may be already using purging compound. So you want to at least get to that level and hopefully exceed.
