Thermochromic PP material can use the temperature difference to control the color change.
The principle of thermochromic PP material
In the PP material, the color transformation is realized by adding a thermochromic pigment. The thermochromic pigment is prepared by an electron transfer organic compound, and the molecular structure of the organic substance is changed due to the electron transfer at a certain temperature so that the color is changed. Intuitively identify the temperature.
Thermochromic PP type
(1) Thermal decoloration type: It is a colored state at low temperature, and changes color from color to colorless when the temperature rises to a certain value.
(2) Thermal hair color type: It is a colorless state at low temperature, when the temperature rises to a certain value, the material changes from colorless to colored.
The application of thermochromic PP material: thermochromic cup, thermostat phone shell etc.
