Internal mold release agents for injection molding and blow molding. Internal mold release agents are added at the extruder. Internal mold release agents are typically of the same chemical classes as anti-static and slip additives. This is not surprising when considering the need for some degree of chemical compatibility in the bulk phase, as well as the ability to migrate quickly to the polymer/mold interface and to possess sufficient thermal stability. Ampacet offers a variety of internal mold release agents, via masterbatch, for both injection molding and blow molding.
Unlike Ampacet internal mold release agents, external products are sprayed onto the mold surface. Inconsistent application of external mold release agents can affect part quality and must be applied every 5 to 10 shots.
