Why do manufacturers of light powders sell cheaper and expensive?

Nowadays technology is so developed, and sunlight color changing powder is gradually applied to various industries. There are more and more light powder manufacturers. How do we judge the quality of materials with different prices on the market? It seems that the powder is similar. Why are some of the more expensive ones more low? The light-changing powders also have the difference between good quality and poor quality. So where are the specific differences?

First of all, good quality light powder printing is better. The good quality light powder is completely different from the poor quality light powder. This kind of organic light change material can be used in the clothing industry and the anti-counterfeiting industry. Because it basically changes color when it meets the sun. In this era, people pursue fashion, and the sun-colored clothes also appear in the clothing industry.

Light-varying powder, after being exposed to sunlight/ultraviolet light, absorbs the energy of sunlight/ultraviolet light, and the molecular structure of the light-changing powder changes, resulting in a change in the wavelength of absorption, resulting in a color change; when the light-transforming powder loses sunlight/ultraviolet energy, Then return to the original molecular structure and restore the cost to the color. This is the principle of color change.

The manufacturer of the optical powder indicates that it is colorless (or the natural color of the product) in the absence of an ultraviolet light source, and is discolored under the environment of an ultraviolet light source (or a mixed color of the product and the color of the product). Most of the products are designed for indoor (no UV) and outdoor (with UV) color changes.

Nowadays, photochromic materials have been used in clothing fabric printing, ceramic mugs, printing, printing and dyeing coatings, plastic injection, plastic extrusion, plastic injection molding, various gifts, advertising materials, children's toys, heat transfer stickers, etc. The life has brought a big impact.
