mask filter material pp granules,
meltblown modified pp resin
Modified Polypropylene Resin making non woven pp filter of FFP3 face mask
The middle lining cloth of a face mask--the meltblown nonwoven cloth is the most critical part. It must filter more than 95% of non-oil particles in air that contains invisible viruses and bacteria , otherwise the entire Face Mask will be a fake product which has no efficiency at all for bacteria filtrattion and face protection!
As a manufacturer to make a meltblown nonwoven fabric of top quality, first of all, you need to choose the right material. PP 1500 - Polypropylene Homopolymer with Melt Flow Index of 1500 g/10min which is suitable for meltblown, is specially modified for this purpose, it has been widely used by the industry because of its processability and quality stability.
Below is the Technical Data Sheet of PP 1500, other technical documents, including MSDS, Rohs and REACH, will be provided upon request.
