eSpin Technologies, Inc. is a high-tech manufacturing company based in Chattanooga, Tennessee. The company provides global leadership in polymeric nanofiber manufacturing technology applicable across the universe of emergent and traditional manufacturing sectors. eSpin's nanofibers are 20-200nm in diameter (about 1000 times smaller than a human hair), have a very high surface area to mass ratio, and can be formed into membranes with very high porosity.

As a platform technology, eSpin’s nanofibers have an incredibly broad range of market opportunities in traditional and emerging segments of industries such as filtration, aerospace, structural composites, healthcare, energy storage, cosmetics, and many others. Nanofibers' unusual characteristics can provide orders of magnitude of improvement in critical product properties when combined with existing technologies by innovatively overcoming many technical hurdles faced by incumbent products.

The eSpin team consists of a small number of highly capable and committed individuals, and an outstanding group of consultants. The company is currently supplying nanofibers for clean room products, nanocomposites, filtration, surgical gowns, biomedical devices, and specialty fabrics, among others. eSpin’s global partners include Fortune 500 corporations, government and military laboratories, research institutions, and select high technology companies around the world.

The company has also recently won grants from the National Science Foundation and the Department of Energy for continued development of nanofiber technology. It has been featured in global industry publications such as Nonwoven World, Chemical Engineering News, and Nature among others.
