Hello all,

I was just wondering if any one here has tried any purging compound from a company called Chem Trend? I'm currently working on a new program that is made out of PA66 Nylon utilizing a orange concentrate. I'm experiencing a lot of black spots/specks in my parts and need some tips on some good purging compound to get the screw, barrel, and hot runner clean. They claim this concentrate can be mixed with your resin and run through the system to dissolve and clean it.
