    DuPont moves into nanocomposites

    NPE: DuPont moves into nanocomposites

    By Andy Beevers in Chicago 23/06/2006

    Its DNM material is based on a different type of nanoclay to those used to date.

    23 June 2006 � DuPont is planning to launch its first nanocomposites, which are based on a proprietary nanoclay technology, next year.

    Dr Nandan Rao vice president, technology at DuPont Performance Materials, told PRW.com that the company�s new nanomaterial, called DNM, is based on a different type of nanoclay to those used to date. �It has an even higher aspect ratio and is not a platelet structure,� he added.

    Thermoplastic nanocomposites incorporating DNM exhibit improvements in mechanical properties, high-temperature performance, barrier properties and processing characteristics, according to DuPont.

    Dr Rao said that the addition of only 1.5% by weight of DNM in a glass-reinforced PET material produced 10-15C improvements in heat deflection temperature. This effect can be used to reduce the glass loading in a compound to achieve the same HDT performance with a lower weight part.

    Other examples presented by DuPont showed how very low loadings of DNM can improve the high-temperature creep resistance and the stiffness-toughness balance of PET resins.

    DuPont plans to introduce its first commercial nanocomposites based on its DNM technology in 2007. �They will be the first in a series of nanotechnology innovations in engineering polymers and barrier packaging materials that you can expect from DuPont over the next few years,� stated Dr Rao.

    The Nanocomposites 2007 conference will take place in Brussels on 14-16 March. For more information on the conference, organised by EPN, visit www.plastics-events.com.

    • Except for the muscle that DD can put behind its sales to the auto industry, this does not seem especially exciting. To the extent that they still require glass fill to get their results, the cost savings are less. Without the platelet structure their UV protection is probably less, if any.
      I liked the concurrent article, also by Andy Beevers, that Maserati is now using a nanoclay thermoplastic for an engine cover part made from MXD 6. (Only UBE is the supplier of the nanoclay.)
      Wedbush Morgan's latest update (last Monday) is modeling a $250,000 revenue for Nanocor in each of the 3rd and 4th quarters of 2006 and $500,000 in Nanocor revenue for each of the 4 quarters in 2007. It would be nice to learn if those numbers are pulled from thin air or the result of conversations with Nanocor' distributors like Colormatrix.
