First, the principle

It is a micro-gel wrapped with invisible materials, color formers and temperature control agents. It can be made into color-changing color materials in different temperature ranges by different temperature-control factor materials.

Second, the product description

A, the principle of discoloration: low temperature is colored and high temperature is colorless.

B. Product range available: -15°C~70°C. Temperature, self-adjustable.

C. Basic color: 15 colors can be provided for each temperature (70 °C only provides black and dark blue). The colors can be mixed with each other, and other color materials can be added.

The color change principle and structure of the reversible sensible thermochromic pigment

The reversible thermochromic pigment 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. The color-changing substance is not only bright in color, but also can change color from the state of "colored ===colorless" and "colorless===colored", which is a heavy metal complex salt complex type and a liquid crystal type reversible temperature change. What the substance does not have.

The application of thermochromic pigments in the price of thermochromic powders in plastic products:

1. R series thermochromic pigments are most suitable for injection molding and extrusion:

R series (plastic grade) is a variety of color-changing pigments developed by the company for plastics. Its characteristics are: thick wall of the capsule, high strength, good heat resistance, easier to disperse evenly, and less residual color during decolorization.

2. Scope of application:

This product can be used for injection molding and extrusion molding of transparent or translucent plastics such as polyethylene (PE), polypropylene (PP), polystyrene (PS), soft polyvinyl chloride (S-PVC), AS and ABS. It can also be mixed with unsaturated polyester, epoxy resin, plexiglass or nylon monomer for casting, molding and curing.

4, color masterbatch:

In mass production, color-changing pigments can be added to polyethylene wax or polystyrene wax to prepare a color masterbatch with a pigment content of 10%, and then mixed with plastic particles. This allows the discoloration pigment to be more uniformly dispersed. For the preparation method of color masterbatch, please refer to the technical data provided by the company.

5, temperature:

The processing temperature should be controlled below 200 ° C, do not exceed 230 ° C, and minimize the heating time of materials. (High temperature, long-term heating will impair the discoloration performance of the pigment).

Temperature change temperature

In fact, the color change temperature of the thermochromic pigment is not a temperature point, but a temperature range, that is, a temperature range (T0 to T1) included from the start of discoloration to the end of discoloration. The width of this temperature range is generally 4~6 °C, and some varieties with high color-changing precision (narrow range varieties, indicated by "N") have a narrow color temperature range of only 2~3 °C.

Usually, we define the temperature T1 corresponding to the color change substantially completed during the constant temperature heating process as the color change temperature of the thermochromic pigment.

2. The temperature of our company's temperature change is: 5 ° C - 8 ° C, 6 ° C - 9 ° C, 8 ° C - 13 ° C, 12 ° C - 14 ° C, 16 ° C - 18 ° C, 21 ° C - 24 ° C, 23 ° C - 27 ° C , 26°C-31°C, 30°C-35°C, 36°C-41°C, 38°C-43°C, 40°C-45°C, 45°C-50°C, 46°C-51°C, 48°C-53°C, 60 °C-65 ° C, 65 ° C -70 ° C, 70 ° C -78 ° C and so on.
