Medlong melt-blown technology is a highly effective method of producing fine and efficient filter media, the fibers can have diameters under 10 µm, which is 1/8 the size of a human hair and 1/5 the size of cellulose fiber.
Polypropylene is melted and forced through an extruder with numerous small capillaries. As the individual melt streams exit the capillaries, hot air impinges on the fibers and blows them in the same direction. This “draws” them, resulting in fine, continuous fibers. The fibers are then thermally bound together to create a web-like fabric. The melt-blown can be calendered to reach a specific thickness and pore size for liquid filtration applications.
Medlong is committed to researching, developing, and manufacturing high-efficiency liquid filtering materials, and providing the customers with stable high-performance filtration materials used all over the world in a wide range of applications.
