Meltblown nonwowens are heavily used in mask applications. An N95 mask or N95 respirator is a particulate-filtering facepiece respirator that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 classification of air filtration. N95-rated filtering facepiece respirators have a filtration efficiency of at least 95% against non-oily particles when tested using the NIOSH criteria. 

Charge Enhancer( Electret) Masterbatches create positive charges on the web resulting increasing filtration efficiency of melt blown nonwowens.

  • Masterset PP 2065 Charge Enhancer Masterbatch is designed for melt-blown applications. PP 2065 CE improves the surface properties after crona treatment of the nonwowen webs.
  • Masterset PP 2065 CE doped maks exhibit excellent charge stability, low pressure drop, excellent dust holding capacity and high filtration efficiency.
  • While the filter efficiency of the neat filter without PP 2065 CE was determined as 92%, the non-wowens with the 2.4 wt% PP 2065 CE showed a filter efficiency value of 96%. (25 ºC, %45 RH with 0.27 μm NaCl fog)
  • PP 2065 CE masterbatch can be used for medical non-woven applications such as masks and protective clothing.
