Melt blowing is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. The randomly deposited fibers form a nonwoven sheet product applicable for filtration, sorbents, apparels, and drug delivery systems. Using the right combination of polymers scientists have been able to produce melt-blown fibers with an average diameter of down to 36 nm.

You’ll commonly find melt-blown materials used in filters. Both filters we offer include melt blown layers.
