DuPont have announced the release of "Light Stabilizer 210," a plastic additive designed using extremely small particles of titanium dioxide, which have been nanoengineered to absorb UV. The company has also applied in the US for regulatory approval for use in the food sector. In testing, LS 210 blocked twice as much UV light as several classes of competitive products, the company said. LS 210 works by absorbing UV rays & changing them into small amounts of heat which dissipate quickly without damaging the structure of plastic. "The key performance advantage of the new light stabiliser is that its extremely small particle size provides much more surface area for UV absorption," the company stated. DuPont has selected the additive as a demonstration case for application of a risk assessment process. The Nano Risk Framework was introduced by DuPont and Environmental Defense introduced in June, a bid to meet scientific and consumer concerns about the technology. The framework is a systematic and disciplined process to evaluate and address the potential risks of nanoscale materials. Light Stabilizer 210 will be available for sale in November, the company stated. DuPont claims to be the world's largest manufacturer of titanium dioxide, a material widely used as a pigment in the coatings, plastics and paper industries.
