Polymer nanofibrous membranes

NnF MBRANE® – PA6 (Nylon 6)

Product description

NnF MBRANE – PA6 (Nylon 6) is a novel kind of nanofibrous membrane produced by industrial production technology operated by Pardam, s.r.o. in the Czech Republic. Nanofibrous layer is deposited on the top of a supporting substrate with air permeating structure made of virtually any material on customers’ request – woven/nonwoven textiles, filtration paper... or without support. Combination of the grammage of nanofibrous layer and a type of the supporting substrate enable manufacturing of filtration membranes with different permeability and filtration efficiency, in accordance to customers demand! The product combines extraordinary properties of nanofiber structure and morphology, e.g. small pores with uniform size distribution, excellent filtration performance and high permeability, with present mechanical properties of supporting material. NnF MBRANE – PA6 (Nylon 6) has very wide application field such as air, water and liquid filtration, biomedical and textile application. For its lightness and breathable nature PA 6 nanofibers are useful for medical applications as a support or barrier material.

  Breathable | High flux | Chemicaly stable with the exception of acids | Biodegradability | Peel-ability – it is possible to use nanofibrous layer without support materialType of the supporting substrate and grammage of nanofibrous layer determine the membrane permeability and filtration efficiency. Those parameters can be modified in accordance to customers demand.

Additional post treatement available:
Lamination of nanofibrous membranes (double / triple sandwich material) | Post treatment with plasma spray (hydrophobic / hydrophilic surface treatment) | Doping with funcionalized particles (Ag, ZnO, TiO2... antibacterial function).

Important notice:

production of composite PA6/PUR membranes in one single layer is also possible. By combination of those nanofibrous materials it is possible to reach unique mechanical and filtration properties of the membrane. Feel free to contact us to obtain samples for evaluation.
