Hot Melt Adhesive Compounding

COMPOUNDING FLEXIBILITY

• NFM’s TEM Series co-rotating, intermeshing twin screw extruders offer ideal shear and mixing properties to hot-melt adhesive compounds.
• NFM’s WE Series counter-rotating, tangential screw design provides thorough mixing of resins with a wide range of viscosities and melting temperatures, designed to generates high shear without high temperature to protect heat sensitive resins.

MULTI-STAGE FEED

• Eliminates the need for pre-blending then high-melt viscosity polymers are introduced first and extruded into a uniform state by the twin-screw action.
• Low-viscosity materials, which can be pre-melted if desired, are added downstream.
• Oil can be injected into the barrel of the compounder in a final stage.
• Continuous compounding action of the twin-screw mixing process improves quality control and produces a uniform hot-melt adhesive.

SHORT RESIDENT TIME

• Twin-screw mixing virtually eliminates the cross linking of polymers that occurs during batch processing when high temperatures are maintained over extended periods. Residence time is often no longer than 15 seconds.

LOW OPERATING COST

• NFM’s hot-melt adhesive compounding extruders are not labor intensive and utilize adiabatic extrusion for minimum energy cost per pound of product.
