NnF MBRANE - Model PUR -Polymer Nanofibrous Membranes
NnF MBRANE – PUR 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! Nanofibrous structure of the membrane posses small pore size, which leads to high filtration efficiency with simulteneously high permeability due to open fibre structure.
This characteristics and strong chemical resistance of PUR predestine this type of membrane for high flux filtration of various gases and liquids with the exception of some organic solvents, as well as filtration of water and air. NnF MBRANE – PUR is also suitable for any nanofiber layer application where flexible, porous, chemicaly stable membrane is needed.

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). Please feel free to contact us for more info.
Water and waste water filtration | Air filtration | Separation membranes
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.
