CIVIL GRADE DISPOSABLE MASKS (BOX OF 50 MASKS)
Our civil grade mask incorporates "melt blown" technology just like N95 and medical grade masks. This technology is the key for excluding viruses. 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. The substantial benefits of melt blowing are simplicity, high specific productivity and solvent-free operation. Choosing an appropriate combination of polymers with optimized rheological and surface properties, scientists have been able to produce melt-blown fibers with an average diameter as small as 36 nm.
These are disposible masks and should not be used more than one day of intensive use, or 2-5 days or casual of intermittant use. If the mask becomes wet, discard it properly.
