Electret Masterbatch for mask meltblown fabric


1.jpg

The purpose of electret is to make the static electricity stored in the meltblown layer of the mask, which can absorb positively charged dust, bacteria, viruses, aerosols and other harmful substances in the air thus improving the filtration efficiency of the meltblown layer in the mask. Javachem®EF-MB is a high-performance electret masterbatch based on high-melting index meltblown PP material, with Javachem®SF fluorosilicon polymer dispersed into PP carrier resin. It is a necessary functional material for manufacturing special meltblown non-woven fabric for masks.

Javachem®EF-MB can increase the density and depth of the charge trapping energy well in the meltblown non-woven fabric with less addition,  effectively release negative ions and store charges to improve the comprehensive filtration efficiency and heat loss resistance of the meltblown non-woven fabric, and reduce the resistance of non-woven products and improve the filtration efficiency of non-woven products at the same fiber fineness and gram weight.

 

Benefits of Javachem®EF-MB
