Meltblown PP Granules Electret Masterbatch

                                               Electret Masterbatch inorganic type for BFE99 melt blown non woven fabrics   

Face Mask used to be a nice-to-have product for people living in urban areas, but it has turned to be an indispensable protective equipment for everyone all across the world since the outbreak of COVID-19 pandemic. A typical medical Face Mask contains three layers of nonwoven cloth, Spunbonded-Meltblown-Spunbonded nonwoven fabrics, among which the middle lining of meltblown fabric plays a crucial role in filtering viruses and bacteria. The mechanism of meltblown nonwoven fabric is to filter 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 during the process 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.

Electret Masterbatch IB-108 is developed and produced by us and has been widely used and accepted by customers in the industry.  Adding IB-108 with mixing ratio of 1~3% to the bulk material of PP UHF1500 which is also developed and produced by us, 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.
