How to Use Commercial Purging Compounds in Extrusion

摘要

Use of commercial purging compounds (CPCs) has become an integral and even more vital part of thermoplastic processing. CPCs have proven to be invaluable tools for addressing market factors such as heavier reliance on just-in-time processing, increased pressure for cost savings in order to remain competitive, and use of more advanced resins, colorants, and additives. CPCs are considered most often for injection molding. However, they also can provide the same benefits to extrusion processors.
