Polypropylene granules UHF1500 for BFE99 melt-blown non-woven fabrics Face Mask
The most important part of a Face Mask is the middle layer cloth of the SMS structure--the meltblown nonwoven fabic, it must filter more than 99% 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.
To make a meltblown nonwoven fabric of top qualoty, first of all, you need to choose the right material - Polypropylene Homopolymer with Melt Flow Index of 1500 g/10min which is suitable for meltblown. PP UHF1500 is specially designed and produced for this purpose and has been widely accepted by the market and the industry.
Below is the Technical Data Sheet of PP UHF1500, other technical documents, including MSDS, Rohs and REACH, will be provided upon request.
