Modified Polypropylene Resin PP 1500 making KN95 mask filter meltblown nonwovens
The outbreak of COVID-19 has made face mask an indispensable product for people to protect themselves from being infected, amomg a face mask the middling lining filter made of meltblown nonwoven fabric is the most important component. 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!
To get the best filter of a face mask, first of all, you need to choose the right material - Polypropylene Homopolymer with Melt Flow Index of 1500 g/10min which is suitable for meltblown process. PP 1500 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.
