Advantage
1. The addition of electret masterbatch makes the fiber more even, the surface smoother and the electrostatic distribution more even in the production process of melting and spraying cloth.
2. Improve filtration efficiency and maintain charge storage period more permanently.
3. Stronger particulate adsorption capacity can make the filtration efficiency of melting spray cloth to oily particulate DOP paraffin oil reach more than 99%, meet GB2626 standard KP100 and European EN149 standard FFP2 and FFP3 indexes, and meet the filtration requirements of higher filtration products exported to Europe and America masks for melting spray cloth.
4. Organic formula system, suitable for most melting and spraying materials, without blocking the spinneret, to improve work efficiency.
Application Realm
It is mixed with the pp meltblown material to produce the middle Layer of the mask to improve the filteration efficiency of the mask .it can well help the meltblown fabric to pass the NaCl test and Paraffin oil test for USA and EU
