Meltblown cloth filter material is adhered together by random distribution of polypropylene ultrafine fibers. The appearance is white, flat and soft. The material fiber fineness is 0.5-1.0μm. The random distribution of fibers provides more thermal bonding between fibers Opportunity, so that the melt-blown gas filter material has a larger specific surface area and a higher porosity (≥75%). After high-pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency, and high dust holding capacity.
