First of all, the answer is, yes.

As we all know, thermochromic powder is a thermosensitive color-changing material that changes color at a specific temperature.

In the global market, the general mainstream temperature ranges are -5℃, 0℃, 5℃, 10℃, 15℃, 18℃, 22℃, 25℃, 28℃, ..., 78℃.

In addition to the mainstream temperatures above, we can also customize some specific temperatures.

However, there are also some customers who need to achieve color development or decolorization in extremely low temperature or ultra-high temperature environments. Can it be found in the Chinese market?

Colored to Colorless Series: At present, in the Chinese market, the high temperature resistant series of thermochromic powders are mainly achromatic series (colored to colorless), which are irreversible/reversible. The maximum temperature can generally reach 70-80 degrees Celsius. In some special cases, the highest temperature can be customized 100~130 degree high temperature series.

Colorless to Color Series: Color series (colorless to colored) and high temperature series are also retro-optical. For many factories, the technical conditions have become more stringent. 

Currently, iSuoChem can produce 130℃, colorless to colored, irreversible temperature-changing inks, which are currently mainly used for paper. This kind of 100~130℃ high temperature series thermochromic powder/ink samples can be taken to test for other uses.
