It's the outbreak of coronavirus that has made Face Mask an indispenbale protective equipment for people all across the world, whether or not a Face Mask can effectively protect human body from invasion of viruses depends on the filtration efficiency of 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 be a fiasco and will Not have any efficiency at all for face protection!
Choosing right material - Polypropylene Homopolymer with Melt Flow Index of 1500 g/10min which is suitable for meltblown, is the first step to make a quality meltblown nonwoven fabric. Besides MFI, other technical data such as Ash Content and Volatile Constituents of the material play important roles in meltblown process, and it must be friendly to both of human body and environment, last but not least, the quality of material must keep stable - lot by lot and day by day - for continuous production of meltblown nonwoven fabrics.
Below is the Technical Data Sheet of our material UHF 1500, other technical documents, including MSDS, Rohs and REACH, will be provided upon request.
