Modified Polypropylene Resin PP 1500 for N95 mask filter melt blown fabric
Face Mask has become an requisite for people to protect themselves from being infected with COVID-19, with the middle layer cloth of SMS structure--the meltblown nonwoven fabric at its core. 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 make a top-quality meltblown nonwoven fabric, 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. 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.
