Chameleon International of Oak Ridge, N.C., has developed color-changing film materials sensitive to temperature.
Chameleon's ChroMyx changes color once certain temperatures are reached, and then reverts to the original color when the temperature shifts back. Chameleon developed the materials in conjunction with Wiman Corp., part of RTP Co.'s sheet and film unit.
ChroMyx film is made by a cast extrusion process of PVC film by Wiman Corp. of Sauk Rapids,
