PP electret masterbatch Z421-ELEKEY
The electret of the electret masterbatch refers to a dielectric material that has the function of storing charges for a long time and releasing negative ions. The stored charge can be a unipolar real charge (space charge) injected from the outside, or a dipole in a polar dielectric Dipole charges formed by sub-ordered orientation, or both types of charges. Increase the electrostatic adsorption and negative ion sterilization capabilities of the mask to effectively block droplets, dust, viruses, etc. below micrometers.
This product is based on a special ultra-high-flow polypropylene resin, using hyperdispersants, and advanced blending and extrusion equipment to make the additives in the masterbatch achieve a micron-level dispersion effect. The use of this product can increase the density and depth of the charge trapping energy trap in the meltblown nonwoven fabric, effectively release negative ions and store charges to improve the comprehensive filtration efficiency and thermal attenuation resistance of the meltblown nonwoven fabric; no new equipment is required, There is no need to greatly adjust the existing meltblown non-woven fabric production process; it will not affect the life cycle and service life of the spinneret; improve the filtration efficiency of the non-woven product under the same fiber fineness and the same weight, and self-extinguish Bacteria performance.
