Meltblown Filter Media

At Hollingsworth & Vose (H&V), we are a premier supplier of advanced materials for high-efficiency filtration applications. One of our core product offerings is meltblown filter media.

What Is Meltblown Filter Media?

A highly effective method of producing fine and efficient filter media is using meltblown technology. Meltblown fibers can have diameters under 10 µm, which is 1/12 the size of a human hair and 1/5 the size of a cellulose fiber.

The process of making meltblown filter media begins with raw synthetic thermoplastic material, such as polybutylterephtelate (PBT), polyethylene terephthalate (PET), or polypropylene (PP). The material is melted and forced through an extruder with numerous tiny nozzles. As the individual extrusions exit the nozzles in a semi-melted state, hot air blows them in the same direction. This extends them, resulting in the creation of very fine, continuous fibers. The fibers can then be mechanically, thermally, or chemically bound together to create a web-like fabric, which can exhibit a number of beneficial properties, including, but not limited to:

  • Absorbency
  • Bacterial resistance
  • Cushioning
  • Filtering
  • Flame retardance
  • Liquid repellency
  • Resilience
  • Softness
  • Sterility
  • Strength
  • Washability

These properties make meltblown fabrics suitable for a wide range of applications. Some of the industries that utilize them include roofing, automotive, agricultural, carpeting, personal hygiene, construction, medical, and upholstery. They can also be combined with other materials to create composites that offer enhanced filtration performance for particular use cases.
