FAQ: Purging Compounds
Chemically active CPCs can be an excellent choice for fast color changes but may not be aggressive enough to thoroughly purge highly contaminated injection systems or highly filled resins. In such cases a purge formulation with a higher viscosity may be required to successfully dislodge a highly filled resin. Additionally, purging a hot-runner system requires consideration of the size of the manifold, gates, and melt channels. There is no “one-size-fits-all” purging compound; a CPC supplier is your best resource to help identify the correct purging formulation and procedure for your needs.
