Purging compounds are specialty compounds added to extrusion or injection molding equipment to clean out leftover polymer residue or pigment residue to change to new production orders efficiently. Purging compounds offer faster color changeover, improved product quality, reduced waste, and downstream cost savings. They help remove previous materials from barrel, screw, nozzle, and molds to avoid contamination.
Purging Compound: A Vital Tool in Plastic Molding Operations
What are Purging Compounds?
Purging compounds are cleaning agents that are injected into plastic processing equipment to flush out residual material from previous production runs. They are formulated with filler materials and thermoplastic binders that resemble the properties of the base plastic resin. This allows them to effectively push out contaminants like residual dried ... Read more
