Modified Polypropylene Resin meltblown grade making nonwoven fabrics for mask
The middle layer cloth of SMS structure--the meltblown nonwoven fabric is the core of a face mask. 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!
In order to make a meltblown nonwoven fabric, 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.
