PP carrier electret masterbatch making middle lining nonwoven fabric of N95 mask
The middle lining of nonwoven meltblown fabric of a face mask plays an essential role in filtering viruses and bacteria. It filters more than 95% 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 electric charges which can be kept as long as possible, and a proper electret masterbatch is critical for this purpose.
Uisng the bulk material of PP UHF1500 together with electret masterbatch OB-168, the meltblown nonwoven fabric comes 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.
