Xingsheng Pearl Temperature Change Powder Introduction

Warm-change powder (temperature-sensitive color-changing material): It is a world-class raw material, and is a micro-capsule material that repeatedly changes color as the temperature rises and falls.

The temperature change powder is prepared from an electron transfer type organic compound system. Electron-transfer organic compounds are a class of organic chromonic systems with a special chemical structure. The color transition of the organic substance is changed by electron transfer at a specific temperature. This color-changing substance is not only bright in color, but also can change the color from the "colored === colorless" state, which is not possessed by the heavy metal complex salt complex type and the liquid crystal type reversible thermochromic substance.

The microencapsulated reversible thermochromic substance is called a reversible thermochromic pigment, commonly known as a temperature-changing pigment, a temperature-sensitive powder or a temperature-changing powder. The particles of the brain-rich and warm-tempered powder pigments are spherical in shape with an average diameter of 2 to 7 microns (one micron is equal to one thousandth of a millimeter). The inside is a color-changing substance, and the outside is a transparent shell with a thickness of about 0.2 to 0.5 μm that neither dissolves nor melts. It protects the discolored material from other chemicals. Therefore, it is important to avoid damaging this layer of the casing during use.

Basic color of warm-change powder: black green 350C, medium green 343C, malachite green 321C, grass green 3275C, black 446C, sea blue 301C, royal blue 072C, golden 102C, golden red 032C, red 1935C, rose red 234C, bright yellow 136C, brown black 5C, peach red 231C, orange red 171C.

Temperature change powder basic temperature: -5 ° C, 0 ° C, 5 ° C, 10 ° C, 16 ° C, 21 ° C, 31 ° C, 33 ° C, 38 ° C, 43 ° C, 45 ° C, 50 ° C, 65 ° C, 70 ° C, 78 °C.

The temperature-changing powder uses the difference in temperature to control the color change. It can be used for screen printing, letterpress, gravure and flat printing. It can be printed on paper, fabric, film, glass, wood, ceramic and other materials.
