About Photochromic polymer

The phenomenon that a substance or a system changes color obviously under the action of an external excitation source is called photochromism. Photochromism means that when compound A is irradiated by light with a certain wavelength, a photochemical reaction takes place to obtain product B with different chemical… Read More »About Photochromic polymer

Application of photochromic polymers

As a new information storage material, photochromic compounds have the characteristics of high resolution and large storage capacity, which can be widely used in frontier fields such as optical information storage, optical conversion devices and optical switches, and have aroused widespread interest. The countries that study photochromic materials… Read More »Application of photochromic polymers

Definition of photochromic polymers

Under the action of light, polymers that can reversibly change color are called photochromic polymers, which belong to polymer materials. According to Krongauz’s definition of a photochromic polymer, a photochromic polymer means that the photochromic pigment molecules are chemically bonded to large molecules. In the strict sense, photochromic… Read More »Definition of photochromic polymers

Method of Mix ink using thermo-sensitive powder

I. Use of pigment:Our products can be directly used to prepare printing inks (screen printing, offset printing, gravure printing and flexography), coatings and for injection/extrusion. Second, the choice of solvent:Temperature-sensitive color-changing powder has good tolerance to gasoline, kerosene, mineral oil, benzene, toluene, xylene, cyclohexanone, benzyl alcohol, turpentine, DBP/DOP… Read More »Method of Mix ink using thermo-sensitive powder
