Much less expensive than other methods of wettability patterning, which requires special equipment.
Highly reliable, highly accurate biosensing at a much lower cost than conventional methods. The test strips are prepared by a photolithographic printing method on metallized plastic films.
Articles can be formed into almost any shape required for an application. The material can be formed, extruded, molded, produced as a sheet, spun, blown, and machined.
The borosilicate glass found in conventional HEPA filters can contaminate sensitive electronic assemblies in clean rooms, as well as being brittle and difficult to pleat during manufacturing. The DuPont technology eliminates these problems.
Filters made using the DuPont technology are low in cost, offer a high dust-holding capacity, provide minimal cross-filter pressure drops for extended periods compared to other filters.
The nanofiber layer has been manufactured at basis weights as high as 40 gsm. The hydrophobic layer (upstream) sheds moisture and the dirt that absorbs it. The downstream nanofiber layer traps particulates as small as 1 micron.
The filter media consists of a conventional scrim nonwoven material (a variety of materials can be used) bound to an electroblown nanofiber layer that can trap particles as small as 1 micron.
