Principle of reflective material is based on the retro-reflection principle can be used to light exposure, and the reflection of light, in real life there are many kinds of reflective material, including leather reflective fabric, reflective, reflective Ribbon, reflective ink, marking paint, etc, of these products continues to enrich our lives, also provide important support for the development of transport.
Surface layer of reflective material (protective film), the reflective layer (functional layer), primary (host), adhesive layer and the bottom layer (layer) composed of multilayer of different substances, which improve the performance of traffic signs, so that it can adapt to the transportation needs of the State around the clock to improve road safety conditions, with high brightness brightness stability, strength and weatherability.
