Inorganic Electret Master Batch for melt blown non woven cloth of N95 Face Masks
The middle layer of a face mask-the meltblown nonwoven cloth, 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.
Adding IB-108, the electret masterbatch , 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.

The Electret Masterbatch with good electrostatic effect, piezoelectric effect, pyroelectric effect. The purpose of the electret is to allow the meltblown of the masks to store classics, so that it can absorb dust, bacteria, viruses, aerosols and other harmful substances in the positively charged air, thereby improving the melting of the mask Spray layer filtration efficiency reaches 95% ~ 99%.
