Thermochromic pigment Reversible color change – three-stage color change powders

Three-Stage Reversible Thermochromic Pigment is a functional pigment that cycles through three color transitions via temperature changes. Its color-changing mechanism is based on molecular structural alterations in electron-transfer-type organic compounds. ‌

Thermochromic pigment Reversible color change – three-stage color changing Principle

This pigment features a microcapsule structure containing a color-changing substance within a transparent protective shell. Electron transfer induces molecular structural changes across different temperature ranges, enabling cyclic color transitions. For example:

‌25°C‌: Displays magenta
‌31°C‌: Changes to blue
‌38°C‌: Returns to yellow ‌
Temperature Range
The three-stage color-changing thresholds are typically 25°C, 31°C, and 38°C, with each range corresponding to a distinct color display. ‌

Thermochromic pigment Reversible color change – three-stage color changing powder Application Areas

Suitable for scenarios such as plastic injection molding and ink substrates, provided processing temperatures remain below 230°C and mixing with fillers like titanium dioxide or carbon black is avoided.
