Virgin polypropylene granules Y1500 in meltblown nonwoven fabric production line
The most important part of a Face Mask is the middle layer cloth of the SMS structure--the meltblown nonwoven fabric, 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.
In order to make a nonwoven cloth with top quality, 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. Scienstein 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.
