Meltblown Nonwovens

The Meltblown technology is one of the most effective ways to make very fine, highly efficient filter media. A meltblown fibre has a diameter of less than 10µm, many times finer than a human hair, which has a diameter of 120µm, or a cellulose fibre of about 50µm.

The raw material is a thermo-plastic synthetic material which is melted and forced through an extruder consisting of a very large number of tiny nozzles. Immediately after exiting the nozzles, the individual filaments are blown by hot air in the same direction while still in their semi-melted state, extending them and creating very fine, endless fibres, within a few milliseconds.

Using this dry-laid process, Neenah Gessner can produce media with weights from 10 – 300g/m².
Alternatively, the meltblown can be directly applied to a carrier media [cellulose or spunbond], producing combination media in one step.

Our Meltblown media can be made of different polymers - just in the way of customer's needs. Our machineries convert Polypropylene (PP), Polyester (PBT), Polycarbonate (PC), Thermoplastic Polyurethane (TPU) or miscellaneous thermoplastics. 

Additionally there are many options who can be choosen, like variable grammage, fiber diameters or surface properties, elongation, resistances (solvent, temperature), electrostatic charge, FDA conformance, anti-bacterial or UV-resistance. 

With our Meltblown Technology we provide tailor-made solutions for our customers, beside our existing product ranges for different applications.
