modified pp materials for meltblown,
n95 mask polypropylene virgin resin
Modified Polypropylene Resin MFI 1500 for melt blown nonwoven cloth of N95 masks
Among the SMS structure of a face mask, the middle layer cloth of meltblown nonwoven fabric is the most important part. It must filter more than 95% of micro-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 face mask manufacturer, 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.
