Environmental news and technical  innovation in the nonwovens sector

APPLETON - Neenah Filtration has launched a new filter media which incorporates the company's patented asymmetric saturation technology and combines the benefits of curing and non-curing resins in one single medium for filter manufacturers.

The two-sided media is also designed to provide different characteristics which, Neenah says, unlocks advantages for its products and converters in a new way.

When processing filter media in the automotive sector, it is important to ensure a certain rigidity of the material for an optimal and fast processing. At the same time, the material should be designed in such a way that pleat lines and dimples created during the pleating process are reliable without damaging the media. The saturation technique demonstrated here gives Neenah Filtration the ability to provide this robustness without jeopardizing the medium’s pleat ability.

Another key function of this “asymmetric saturation” or ability to combine different resin systems on one media is that it allows Neenah to tailor-make its media to meet individual customer needs.
