    RICHARDSON, Texas, Jan. 12 /PRNewswire/ -- Zyvex today announced that
 Thomas Swan & Co. Ltd., and Pyrograf Products, Inc. have successfully met the
 requirements of the Zyvex Supply Chain Certification program for single-wall
 carbon nanotubes and carbon nanotube fibers (respectively).  Zyvex's
 comprehensive program verifies quality and consistency using market-accepted
 analytical tests.
     Thomas Swan is one of the UK's leading performance chemical manufacturers.
 Their single wall carbon nanotubes (SWNTs), marketed under the Elicarb(R)
 trademark, can now be incorporated into Zyvex's NanoSolve(TM) additives and
 concentrates for polymer composite applications.
     Pyrograf Products, Inc. (PPI), is one of the world's leading producers of
 carbon nanofibers.  PPI has the exclusive license to produce and distribute
 the high-quality, multifunctional Pyrograf(R)-III carbon nanofibers, developed
 by PPI's research affiliate, Applied Sciences, Inc. (ASI).  The Pyrograf-III
 carbon nanofibers, developed under the Department of Commerce's Advanced
 Technology Program (ATP), can now be incorporated into Zyvex's NanoSolve
     "Our customers demand quality and reliability.  As such, we demand quality
 raw materials for our NanoSolve products," said Zyvex President Thomas A.
 Cellucci, Ph.D., MBA.  "Pyrograf Products has demonstrated their ability to
 manufacture high-quality carbon nanofibers 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 defense and aerospace communities to
 use our carbon nanofibers 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 nanofibers 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
 defense 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.
     The Supply Chain Certification process is an integral part of Zyvex's
 ability to provide high-quality nanomaterials solutions for customer
