Braskem announces the deposit of new patent in nanotechnology

28-Jul-2006

Braskem has deposited its second patent related to nanotechnology in Brazil. Nanotechnology is one of the most promising frontiers in the scientific area of polymers and materials in general. Besides this initiative, the company has just made the international deposit of its first patent related to this technology.

Nanocomposites are resins that receive nanoparticles, about 50 thousand times smaller than a strand of hair, that afford the products greater physical properties, such as 30% greater rigidity, more shine and greater resistance to impacts.

The new patent concerns the development of a new production process for polypropylene and polyethylene nanocomposites through the polymerization reaction obtained directly in the reactors, or in situ, in technical terms. This process, developed by the Braskem Innovation and Technology Center in Triunfo/RS in partnership with the UFRGS, will initially attend to the high performance package segment. This is the case, for example, of packages that require fat barriers or complete sealing to increase the shelf life of products such as coffee and industrialized snacks, preserving their original characteristics, aroma and crunchiness, included.

Braskem's first patent in nanotechnology, which was deposited in the Brazilian market in 2005, now gains an international scope. It refers to the development of a polypropylene production process to which nanocomposites are added and it has just been deposited in the World Intellectual Property Organization (WIPO) through the PCT - Patent Cooperation Treatment.
