Why Melt Blown Adhesives for Filtration Media are a Smart Option

Melt blown, nonwoven fabrics are becoming increasingly used in today’s industrial manufacturing applications. While they are ideal for a range of end-use products, from medical fabrics to sanitary products, filtration media continues to be the largest application.

Learn about the melt blowing process to understand why it is a smart option for filtration media.

Melt blowing is a process that extrudes molten polymer resins with high velocity air. This air is heated and enables the resins to form fine fibers, which, in simplified terms, collect onto a screen and create a nonwoven web, offering the following properties:

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

These qualities make them well suited for needed filter characteristics.

Why are Melt Blown Adhesives Good for Filtration Media?

Due to melt blown adhesives’ properties, they are able to offer certain advantages over other options. These include:

  • 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. These benefits, in addition to increased efficiency, make them ideal for filtration media applications.
