Why You Need Melt Blown Adhesives for Filter Media

Melt blown bonding is becoming increasingly used in filter media assembly applications. Get in the know on why this is the case and how melt blown adhesives can offer you distinct advantages.

Melt blowing extrudes molten polymer resins with high velocity air. The air is then heated and enables the resins to form fine fibers. This means they collect onto a screen, creating a nonwoven adhesive web that offers the following properties:

  • High surface area
  • Smooth surface texture
  • Continuous fibers in length
  • Randomized fiber layer
  • High opaqueness

These qualities make the melt blown webs well suited for needed filter characteristics.

Why are Melt Blown Adhesives Good for Filtration Media?

Melt blown adhesive properties enable them to offer distinct advantages over other options for filtration media bonding, such as:

  • Enhanced filtration efficiency
  • High porosity
  • High dirt holding capacity

These advantages are due in large part to two reasons:

  • Melt blown adhesives do not deeply penetrate the filter media, which would otherwise impact efficiency.
  • Melt blown adhesives’ randomized fiber layer enables it to be highly porous.

Additionally, melt blown solutions are versatile, easy to use and reliable, making them ideal for filtration media applications.
