Electret masterbatch of PP carrier for BFE99 melt-blown non-woven fabrics
The outbreak of COVID-19 epidemic has turned Face Mask from a nice-to-have to a must-have product for people all across the world, a typical medical Face Mask contains three layers, SMS fabrics, among which the middle lining of meltblown fabric plays an essential role in filtering viruses and bacteria. The mechanism of meltblown nonwoven fabric is to filter more than 99% of the particles in air which contains viruses and bacteria through electrostatic absorption, therefore the meltblown fabric needs to get electret treatment to make sure it contains sufficient electret charges which can be kept as long as possible.
Specially designed and produced by us to serve this ppurpose, Electret Masterbatch OB-168 when using together with the bulk material of PP UHF1500, makes the meltblown nonwoven fabric come out with Bacteria Filtration Efficiency ( BFE) at 95% and as high as up to 99.99%, the higher mixing ratio, the higher BFE, and this BFE is almost permanent, won't fade out as time passes.
