US Patent 7635728 - Flame retardant polymer nanocomposites

http://www.freepatentsonline.com/7635728.html

This patent is from Huntsman Advanced Materials Americas and is based on the finding that flame retardancy of polymers can be enhanced by including nanoclay particle filler. Claim 1 reads:

1. A process for the manufacture of a cured article which comprises admixing at least one expandable particulate material which expands on the application of heat with at least one particulate nano-filler and at least one curable monomer, oligomer and/or polymer to form a mixture and subsequently curing the mixture.

US Patent 7579399 - Plastic forming tool including nanoparticles

http://www.freepatentsonline.com/7579399.html

Throughout human history shaping tools have taken a variety of forms including stone, metals, alloys, and diamond. This patent from Huntsman Advanced Materials Americas appears to broadly claim a new form of shaping tool based on nanoparticle doped plastics which may be cheaper, more lightweight, and stronger than prior materials. Claim 1 reads:

1. A tool which consists of a plastic material with nanoscale particles and a material with gliding properties embedded in the plastic material and wherein the tool is in the form of a forming tool.
