Melt blown fabric is a filtering material mainly made of polypropylene. Its fiber diameter can reach 1-5 microns. These ultra-fine fibers with unique capillary structures increase the number and surface area of fibers per unit area, resulting in excellent filtration, shielding, insulation, and oil absorption properties of melt blown fabrics. They can be used in fields such as air and liquid filtration materials, isolation materials, absorbing materials, mask materials, insulation materials, and wiping cloths. Today, BAIJIAN will introduce relevant testing knowledge to everyone. BAIJIAN provides authoritative and effective testing reports, mainly covering food, agricultural products, environmental soil, environmental protection, industry standard training, retail services, etc., providing convenient testing services for you.
