Zyvex Confirms Nanotube Suppliers for Polymer Composite Applications

14 January 2005

Zyvex have added Thomas Swan & Co. Ltd. and Pyrograf Products Inc. to their supply chain for single-wall carbon nanotubes and carbon nanotube fibres.

UK chemical manufacturer, Thomas Swan, can now incorporate their single wall carbon nanotubes (SWNTs), marketed under the Elicarb trademark, into Zyvex's NanoSolve additives and concentrates for polymer composite applications.

Pyrograf Products, Inc. (PPI), producers of carbon nanofibres has the exclusive license to produce and distribute the high-quality, multifunctional Pyrograf-III carbon nanofibres, developed by PPI's research affiliate, Applied Sciences, Inc. (ASI). The Pyrograf-III carbon nanofibres, developed under the Department of Commerce's Advanced Technology Program (ATP), can now be incorporated into Zyvex's NanoSolve materials.

Zyvex President Thomas A. Cellucci said that ""Pyrograf Products has demonstrated their ability to manufacture high-quality carbon nanofibres and Thomas Swan & Co. has demonstrated their ability to manufacture high-purity single-wall carbon nanotubes. We are satisfied that both companies can scale their production technology to match the expected increase in industrial demand.""

""We are delighted to have obtained Zyvex's seal of approval,"" said Harry Swan, Nanomaterials Business Manager at Thomas Swan. ""Quality control and consistency of material are vital to ensure the successful uptake of carbon nanotubes in a wide range of commercial applications.""

""There is increasing interest in the defence and aerospace communities to use our carbon nanofibres to impart enhanced thermal, mechanical and electrical properties in high-performance composite systems,"" said Thomas W. Hughes, General Manager at Pyrograf Products. ""Zyvex's NanoSolve technology helps produce a highly dispersed network of carbon nanofibres within various polymer systems. This attractive feature enables our growing user base to design and build customizable, multifunctional composite materials and components. This is a win-win for us, for Zyvex, and for our end users in the defence and aerospace communities.""

Thomas Swan & Co. and Pyrograf Products are the second and third companies to be certified under this program. Zyvex is working with a number of other leading nanotube providers and will continue to announce additional vendors as they become certified.
