New nano product protects plastic from sunlight
DuPont is about to release a product made using nanotechnology that will protect plastics from sunlight.
DuPont made the announcement yesterday during the launch of a system of procedures to help companies evaluate the safety of nanotechnology engineered products.
The company calls its product DuPont Light Stabilizer 210, a new titanium dioxide-based material. It is designed as sun protection for plastics.
Overlong exposure to sunlight can break down components in plastic packaging, causing a change in colour.
Not all of the particles in this product fit the specific definition of nanomaterials, since a significant fraction of the materials is larger than the threshold 100 nanometer size, DuPont said.
