Ultra FoamMix EX
Description
A Nordson Ultra FoamMix Extruder is the
first choice when processing “difficult” adhesives
like Polyamide, Polyester or Polyolefin (APAO).
These adhesives ask for a closed system to avoid
degradation of the adhesive through carbonization and
consequently loss of bonding performance or other
problems caused within the system.
Extruders enable homogeneous melting in a fully
closed “melt‐on‐demand” system to provide a safe and
reliable application process.
Nordson extruders offer the fastest, easiest adhesive
changes possible compared to other melters without
time‐ and cost‐intensive cleaning procedures.
The Nordson Ultra FoamMix EX Extruder offers a
low‐maintenance, user‐friendly solution to improve
mechanical properties of adhesives and provide material
savings with a variety of high‐performance materials.
Demanding materials like Polyamide or Polyolefin as
well as other thermoplastics are foamed by low pressure
nitrogen injection without chemicals so they retain
their basic physical properties.
Straight‐forward PLC controls provide a user‐friendly
touch‐screen programmed to display and operate in
local languages. The Ultra FoamMix Extruder controls
easily integrate with the parent machine controls.

Gas content of foamed materials can be adjusted
to control mechanical properties such as material
durometer, compression set resistance and flexibility.
Advanced Application Technology
The Nordson Ultra FoamMix process dramatically
improves the performance of most hot melt adhesives
by mixing them with gas, creating a homogeneous
solution. As the material is dispensed, the gas expands
to create a closed-cell foam. The foamed material is
applied like the more conventional approaches, but
provides the following benefits:
• Reduced adhesive consumption of up to 50 percent.
• Increased open time provides greater process flexibility.
• Faster set time for increased line speeds and production
rates. Labor is reduced and less warehouse space is
required for inventory.
• Volumetric increase for greater gap filing capabilities.
• Improved wetting increases the ability to bond
impervious surfaces and enhances application
versatility.
• Lower heat density helps reduce heat damage while
improving operator safety.
• Reduced sagging or running for uniform adhesive
thickness.
• Increased penetration creates stronger bonds and results
in fewer rejects.
