Masterbatch series

Ordinary electret masterbatch

  By adding hyperdispersant and other effective components, a high-fluidity functional masterbatch with high charge energy density and stable charge storage is obtained.

Product advantages

        ⊙ The filtration efficiency can easily reach more than 95% (addition amount is 2%-5% (mass fraction); when the equipment and process are in good condition, the filtration efficiency can easily reach more than 99%)

        ⊙ Long-lasting charge retention (the melt blown cloth can be stored on shelves more than 3 years)

        ⊙ 95L/min flow rate, double-layer detection, filtration efficiency can reach more than 95%

⊙ No need to change the meltblown material production process parameters (the melting index is between 1200-1600)

⊙ Washing without power loss (use with our melt blown material, soak in water for more than half an hour, the charge will not attenuate)

Product application
Melt blown cloth application

        Electret masterbatch is a special functional masterbatch used with electret equipment. It uses polypropylene as the base material and is an essential functional material for the manufacture of special melt blown cloth for masks. Its magic is that adding a small amount of electret masterbatch can increase the density and depth of the charge trapping energy trap in the melt-blown non-woven fabric, effectively release negative ions and store charges, and improve the integration of the melt-blown non-woven fabric. The purpose of filtration efficiency and thermal decay resistance performance. Under the condition of the same fiber fineness and gram weight, it can reduce the resistance of melt blown cloth products and improve the filtering efficiency of melt blown cloth products.

        It is worth noting that the effect of electret is related to polypropylene raw materials, production process, fiber size, weight, electret equipment, electret power supply voltage, etc. It can be used in batches only after the actual trial test is qualified.
