Reflective®A special powder made of white or gray glass particles (reflective powder) is combined, for example, with dye that covers knitwear or fabric. This creates a durable, uniform material that can be used as inserts in clothing or as a base material for, for example, a jacket. Reflective paint can also be used to create prints. A reflective element, like glass, reflects an intense beam of light at the same angle or in a diffused manner, making it more visible. The reflection effect increases in intensity in twilight or darkness.
