Ever notice how some white objects seem to just glow? Chances are Eastman's Eastobrite™ optical brighteners live somewhere in the mix.
Most polymers are inherently yellow, though the human eye perceives blue-white to be cleaner and more brilliant than yellow-white. Locking Eastobrite™ OB-1 into the structure creates that sharp, untainted blue-white glow admired in everything from dress shirts to toothbrush bristles.
Over the years OB-1 has been used to enhance the optical appeal of golf balls, kitchen appliances, synthetic leathers, floor tiles, counter tops, credit cars, and plastic bottles. The difference is measurable and we know it when we see it.
Beyond color brilliance, OB-1 offers designers numerous possibilities to differentiate a product, even enhancing security where the increasing ubiquity of UV light to authenticate documents adds another dimension to its flexibility.
Everything from backlighting mobile phone keypads to giving prescription medicine bottles UV protection without obscuring the contents is possible with the addition of even a tiny amount of the OB-1 color enhancement solution.
