Meltblown plant for nonwoven fabric production

    What is Meltblown Fabric, and how does it work?

    Meltblown is an innovative nonwoven manufacturing technology that produces ultra-fine fibers from thermoplastic resin, predominantly for use in high-performance filter media. But how does it work? In the meltblown process, a thermoplastic polymer is melted and extruded through a die having very fine nozzles. Subsequently, a high velocity air-stream stretch the molten strings of polymer. The resulting fibers are very fine and lead to very dense nonwoven fabric with ideal properties for filtration. Meltblown nonwoven fabrics are not only used in air and liquid filtration but also in numerous other fields like medical engineering and automotive.

    Meltblown: efficiency and reliability in micro filtration

    Meltblown filter media are characterized by their exceptional filter performance. They are capable of efficiently removing the finest particles, dust and other pollutants. Microfiltration is particularly important in applications where maximum purity is required, be it in air purification, in water filtration or in medical devices. Due to the fibers’ high density and their specific structure, meltblown filter media can trap micronsized particles, making them a preferred choice for precision filtration solutions.

    Advantages of meltblown filter media

    In filtration technology, meltblown filter media offer a host of advantages in filtration technology, such as

    • High filtration performance: Given the fine fibers, even the smallest particles can be filtered out of the air or a liquid.
    • A wide range of applications: Meltblown technology is used in many different industries ranging from air purification to water treatment and medical devices. 
    • Efficient production: Sandler meltblown filter media enable a rapid production of filters with excellent performance.
    • Adaptability: The structure of the filter media can be customized to specific requirements.
