mask melt blown polypropylene granules,
pp filter granules for meltblown
Clear Polypropylene granules of MFR 1500 making meltblown nonwoven fabrics BFE99
Among the typical SMS structure of a face mask, the most importat part is the middle lining-the meltblown nonwoven fabric which acts as a filter, it must filter more than 95% of micro-particles in air with diameters below 2.5 micron, otherwise the Face Mask will Not have any efficiency at all for face protection, though it looks like pretty normal in appearance.
PP UHF1500 is specially designed and produced for this purpose and has been widely accepted by the market, face mask made of this material is very easy to reach the BFE level of 95% minimun and can be kept for more than 1 year without any loss of efficiency..
Below is the Technical Data Sheet of PP UHF1500, other technical documents, including MSDS, Rohs and REACH, will be provided upon request.
