face mask filter polypropylene granules,
mask meltblown plastic pellets materials
Polypropylene raw material PP resin for mask filters of nonwoven cloth meltblown
Face mask has become an essential protective equipment for people all across the world. The middle layer cloth of a face mask - meltblown nonwoven fabric, plays the most important role of viruses and bacteria filtration, 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!
It's not an easy job to make a top-quality meltblown nonwoven fabric, first of all, you need to choose the right material - Polypropylene resin with Melt Flow Index of 1500 g/10min. Besides MFI, other technical data such as Moisture Content and Volatile Constituents of the material also matter in meltblown process, last but not least, the quality of material must keep stable for continuous mass production.
Below is the Technical Data Sheet of PP 1500, other technical documents, including MSDS, Rohs and REACH, will be provided upon request.
