1. Introduction and the Principle of Color Changing

Memory Type Thermochromic Material is a color-change-reversible material with memory effect. It changes color when temperature is above 55℃ and recovers color when temperature drops below 0℃.

1. As the picture shown below: The material is colored at 25℃. The color starts to fade at 55℃ and disappears at the range 58~62℃ (depends on color). The color will not reappear until temperature drops below 0℃.

(IT: Increasing Temperature; DT: Decreasing Temperature)

2. As the picture shown above: The material is colorless at 25℃. The color begins to show at 0℃ and 100% appears at the range -10~-15℃ (depends on color). The color will not disappear until temperature reaches 55℃.

2. Features

1.Color of the material can be set—in the range of 0℃ to 55℃, the material can be set to colored or colorless.

2.Can be used as an irreversible material. For example, erasable ink.

A. Applications:

Ink, paint, printing, textile…etc.

B. Color:

Red, rose red, magenta, orange, yellow, charm green, green, blue, turquoise blue, dark blue, violet, black and brown.

3. Form:
