DuPont today introduced DuPont™
Light Stabilizer 210, a product designed as sun
protection for plastics. It is an ultrafine/nano titanium dioxide that
provides a low cost, high performance alternative to competing products
and delivers superior broad-spectrum ultraviolet (UV) blocking
performance against UVA and UVB rays. It features low chemical
interaction with other ingredients both initially and upon UV exposure.
DuPont™ Light Stabilizer 210 is designed for a broad range of
plastics applications including films, packaging, construction and
The product uses extremely small particles of titanium dioxide
to efficiently absorb ultraviolet light, protecting plastic and
anything it covers from the sun’s damaging rays. The key
performance advantage of the new light stabilizer is that its extremely
small particle size provides excellent scattering and absorption of UV
light. Further, the small size titanium dioxide does not significantly
pigment the plastic allowing UV stable parts that can be produced in a
wide variety of colors.
Because a sizeable percentage of titanium dioxide particles in
the product are nanoscale, it was selected as a demonstration case for
application of the Nano Risk Framework introduced by DuPont and
Environmental Defense in June. The Framework is a systematic and
disciplined process to evaluate and address the potential risks of
nanoscale materials. DuPont™ Light Stabilizer 210 is the
first product to be commercialized after applying the Framework.
Titanium dioxide is widely used as a pigment in the coatings,
plastics and paper industries.
DuPont is the world’s largest manufacturer of TiO2.
DuPont™ Light Stabilizer 210 is the first in a family of
products based on breakthrough DuPont titanium dioxide process
technology. It will be available for sale in November.
DuPont™ Light Stabilizer 210 is an additive designed
to help protect plastic products from cracking, fading and other types
of solar degradation. Potential applications include sporting goods,
outdoor furniture, fabrics and carpet fibers – virtually any
plastic product that will be exposed to sunlight. It also can be used
in plastic films and sheeting to protect plants in greenhouses or
packaged goods from UV light. In testing, DuPont™ Light
Stabilizer 210 blocked twice as much ultraviolet light as several
classes of competing products.
“Many existing light stabilizers on the market today
can migrate from the plastic over time reducing their
effectiveness,” said Gary K. Whiting, global venture manager
for the new product. “Unlike some conventional light
stabilizers, testing has shown that DuPont™ Light Stabilizer
210 does not migrate out of the plastic under normal conditions, so
products incorporating it have a much longer useful lifetime.”
The development of DuPont™ Light Stabilizer 210 is
an example of DuPont Nanoscale Science & Engineering, an
emerging technology domain that is creating new growth opportunities
across many sectors of the DuPont business portfolio. The application
of new tools and techniques for the measurement, characterization and
control of nanoscale features provides the ability to more precisely
tailor known materials to more effectively deliver desired properties
and to enhance functional benefits. Nanoscale Science &
Engineering further strengthens the company’s integrated and
diverse technology capabilities to create high performance, novel
products that meet current and future market needs.
