UV-detecting beads change color when sunlight passes through Tritan™ TX2001 plaques. Demonstration that sunlight can pass through a sealed pouch formed from Tritan™ TX2001 to cause the UV-detecting beads to change color. A. Unexposed beads in Tritan pouch. B. Beads in Tritan pouch exposed to natural sunlight. C. Beads in Tritan pouch exposed to natural sunlight through a window. A color change in the beads shows that UV radiation has been captured by a bead. The change to one color versus another color has no significance.
