NnF MBRANE - Model PVB -Polyvinylbutyral Nanofibrous Membranes
NnF MBRANE – PVB (Polyvinylbutyral) is a novel kind of nanofibrous mambrane 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... Combination of the grammage of nanofibrous layer and a type of supporting substrate enable manufacturing of filtration membranes with different permeability and filtration efficiency.
Nanofibrous membrane posses small pore size with simultaneously high permeability due to its open fibre structure. Basic feature of this material among others is its hydrophobic – hydrophilic bivalent character, which enables to dissolve this material in alcohols, but does not allow it to swell in water. This leads to long-term biodegradable material suitable for environmentally and health-friendly applications. This material has also a great perspective for doping of fibers with various functional components with slow releasing properties, such as scents, antibacterial or medical compounds as well as any type of nanoparticles.

Important notice:
Production of two layer polymer nanofiber membrane (combination of polymers from our portfolio) in one production step is also possible (mechanical and functional properties improvement).
