PP carrier electret master batch for BFE99 melt blown filters of FFP3 face masks
The meltblown nonwoven fabric is the most important part of a face mask, it acts as a filter to prevent more than 95% of the particles in air which contains 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 proper electret masterbatch is critical for this purpose.
The organic type Electret Masterbatch OB-168 is specially developed and produced by us. Mixing OB-168 with bulk material of PP UHF1500 during the process, 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.
