How to Use Purging Compounds Effectively

Today, you can easily come across a wide range of commercial purging compounds to select from, and CPCs can be grouped into many types of or classes pertaining to the way they work. Mechanical and chemical purging compounds are the most popular types, and there’re some more up-to-date “hybrids” that integrate both chemical and mechanical traits.

Mechanical purging compounds look to be the best kind of purge when a processor want to do color changes or material changes and get rid of contamination. As they don’t need any soak time, they’ve an edge over chemical purge. However, where machine dead spots are a concern in some applications, this soak time may prove to be useful as it gives the purge greater time to deal with these difficult-to-clean regions.

Hybrid purging compounds might demand smaller quantity of purge primarily, which is useful for simple changeovers. But might need more than one purges for more densely-contaminated machineries. Eventually, the best purge is one that has been tried and tested and is proven to be effective. Since most reputable CPC supplier offer Purging Compounds Free Sample, processor need to check as many different purges as feasible.

Can I use purging compound for other uses except color& material changes?

Yes of course! Purging materials need to be employed prognostically as an important part of a “preventive maintenance” program. For instance, processor can use purge to shut down & seal an extrusion barrel or injection molding. The advantages are double: 1) offering further cleaning at the time of shutdown; and 2) stopping carbonization, which usually emerges on start-up. And, while regular purging is an excellent way to avoid screw-pulls, every so often they’re compulsory. In this circumstance, a more aggressive grade of purging compound can simplify the screw-pull by offering extreme cleaning, thus decreasing the amount of time & effort needed.
