Bayer MaterialScience LLC has announced that it has licensed its Aura [TM] infusion technology exclusively to Radco Infusion Technologies LLC for worldwide use.

Bayer says that the Aura technology "offers a cost-effective and environmentally responsible way to improve the UV protection of injection molded or extruded polycarbonate parts ... Because ultraviolet (UV) light attacks polycarbonate at the surface, UV protection is most effective when concentrated there. Yet, with traditional compounding of additives it is not possible to concentrate protection at the surface. This limits UV absorber effectiveness in outdoor applications, such as lenses and covers for lighting fixtures, where protection from sunlight is essential to durability and clarity."

Bayer adds: "The infusion of UV additives via Aura infusion technology utilizes the same process used to add custom colorants. In this new twist, finished plastic parts are immersed in a mostly aqueous solution containing UV additives. The parts are removed from the solution after a short period of time, rinsed with water to remove excess solution from the surface and then dried to produce a market-ready product." www.bayer.com.
