Thermochromic pigment is a kind of magical chemical material that can change its color according to the change of ambient temperature. Thermochromic pigments are used in many fields, such as food packaging, cosmetics, clothing, interior design, etc. The working principle of heat-sensitive color-changing pigments is that when the temperature changes, the chemical bonds between the..

Thermochromic powders are prepared from electron transfer organic compound systems. The temperature-changing powder changes the molecular structure of the organic matter due to electron transfer at a specific temperature, thereby realizing color change. Thermochromic powder is not only bright in color, but also can achieve color change from “colored to colorless” state, which is not..
