Meltblown technology is one of the most effective methods for producing fine, highly efficient filter media. Meltblown fibers can achieve diameters of less than 10 microns—approximately one-twelfth the size of a human hair and one-fifth the size of a cellulose fiber—allowing for superior filtration performance.

The process begins with raw synthetic thermoplastic materials such as polypropylene (PP), polyethylene terephthalate (PET), or polybutylene terephthalate (PBT). These materials are melted and extruded through a die containing numerous microscopic nozzles. As the molten streams emerge, they are simultaneously stretched and attenuated by hot, high-velocity air, creating ultra-fine, continuous fibers. These fibers are then collected and bonded—mechanically, thermally, or chemically—forming a highly uniform, web-like non-woven fabric ideal for critical filtration applications.
