Melt-blown cloth is mainly made of polypropylene as the main raw material, the fiber diameter can reach 1 ~ 5 microns. Void, fluffy structure, not easy to fold, with a unique capillary structure of microfibers increase the number and surface area of fiber per unit area, so that melt-blown cloth has good filter, shielding, insulation and oil absorption. It can be used for air and liquid filtration materials, isolation materials, absorbing materials, mask materials, warm materials, oil absorbing materials and wiping cloth and other fields.
