PP carrier masterbatch for electret treatment of melt blown non-woven fabrics
It's essental for everyone of us to wear a face mask when going out at this pandemic season. A typical Face Mask contains three layers, Spunbonded-Meltblown-Spunbonded nonwoven fabrics, among which the middle lining of meltblown fabric plays an essential role in filtering viruses and bacteria through electrostatic absorption, the meltblown fabric needs to get electret treatment to make sure it contains sufficient electret charges which can be kept as long as possible, and a suitable electret masterbatch is critical for this purpose.
The meltblown nonwoven fabric comes out with Bacteria Filtration Efficiency ( BFE) at 95% and as high as up to 99.99%, when using Electret Masterbatch OB-168 together with the bulk material of PP UHF1500, the higher mixing ratio of OB-168, the higher BFE of the mask, and this BFE is almost permanent, won't fade out as time passes.
