PHOTOCHROMIC MATERIAL Change color with UVA radiation.  THERMOCHROMIC MATERIAL Change color with temperature.  FRAGRANCE MICROCAPSULE MATERIAL Long lasting microcapsules release fragrance longer than six months.  LONG LASTING GLOW IN THE DARK MATERIAL Store light and heat from conventional sources, and glow in the dark.  INVISIBLE FLUORESCENT MATERIAL It is white or invisible under conventional visible light and appears colorful fluorescence under UV/IR light.

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 42℃ 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 42℃ 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 42℃.

2. Features

1.Color of the material can be set—in the range of 0℃ to 42℃, 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.
