US Patent 7553898 - Flame retardant plastics with nanostructured filler

This patent for the Research Foundation of the State University of New York teaches a flame retardant polymer composite incorporating nanomaterials and resistant to degradation when exposed to UV radiation. Claim 1 reads:

1. A flame retardant composition comprising:

from about 30% to about 50% by weight of a polyolefin;

from about 10% to about 25% by weight a brominated polystyrene or from about 30% to about 40% by weight decabromodiphenyl ether;

from about 10% to about 30% by weight of an exfoliated nanoclay; and

from about 5% to about 15% by weight carbon nanotubules or metal oxide fillers in the nanometer particle range.
