This product is an electret masterbatch with high melting index homopolypropylene as the carrier. The high-efficiency electret in the masterbatch can effectively increase the long-term charge trapping effect in the meltblown cloth, so that it can absorb (+) positive charges. Dust, bacteria, viruses, aerosols and other harmful substances in the air, thereby improving the filtration efficiency of the meltblown layer in the mask (up to 95%-99%) is an essential functional material for the manufacture of special meltblown non-woven fabrics for masks .

Use ratio:
*BFEseries：1.0%-1.5%
*PFEseries：1.5%-2.0%
*N95/N98/P1/P2series：2.5%-4.0%
Instructions:
①Mix with polypropylene resin according to the appropriate proportion or adjust the proportion with the master batch feeding metering device.
②After stable production, the non-woven fabric is charged by applying voltage through the host device.
Precautions:
*The effect of electret is related to polypropylene meltblown raw material, production process, fiber fineness, gram weight, electret equipment, electret power supply voltage/power supply distance, etc., and it can be used in batches only after passing the actual use test.
