We use our own electret masterbatch, and charging equipment, the product balanced the filtration and pressure. It align to FFP1
The product is Melt bond non wovens, it has strong tensile strength, our own static charging equipment can help the non woven keep more electret and keep them long, which lead to high filtration ratio. It is very good material for air filtration product like mask, industrial filtrate equipment etc..
The unit weight of the non woven can varied from 20 to 100.
