Nonwoven Media Products

Using wet-lay machines (paper machines) we form non-woven media from fibers (polymer, ceramic, glass, metal alloys, carbon, etc…).  This process can be done at lab scale on handsheet molds pilot scale on small paper machines and production scale on large paper and non-woven machines.  We have run our media at all of these scales.

The non-woven may contain high surface area particulate (catalysts and sorbents) for molecular level chemical reactions, or be free of these.  A typical non-woven is sintered after production, but polymer non-wovens are usually sintered during the drying process.  Air-laid non-wovens may be formed, but we typically use the wet-lay process due to its superior uniformity.

Typical sheets have fiber void volumes of 95% before calendaring (pressing), but the void may be filled with high surface area particulates.
