Do you know the colour changing wristbands? There are two kinds of colour changing wristbands in our factory. One is UV silicone wristband and the other is glow in the dark silicone wristband.
UV silicone wristband is a photochromic product. After sunlight/ultraviolet irradiation, it can absorb the energy of sunlight/ultraviolet ray, produce the change of molecular structure, cause the change of absorption wavelength, and produce the change of colour . When the energy of sunlight/ultraviolet ray is lost, the original molecular structure will be restored and the cost-effective colour will be restored. Normally the UV silicone wristbands are transparent, but when we put them under the sunlight they will change to purple or blue colour .
The glow in the dark silicone wristband is to add noctilucent powder in production. After being irradiated by natural light, sunlight, ultraviolet light and so on, the noctilucent powder stores the light energy, stops illumination, and then slowly releases it in the way of fluorescence. Therefore, in the night or in the dark, it can still see the light, lasting for several hours to more than a hours.
Now we welcome all customers to come to get the samples of colour changing wristbands free of charge.
