Belonging to the first and second grade reflective film in the transportation industry standards JT / T279-1995 in. It differs from project-level reflective principle and the principle of high-strength grade reflective glass beads reflective film used, but the use of the latest technologies microcrystalline cube reflector. Microcrystalline cube after each coupling arrangement, there will be 930 or more microcrystalline cube corner body in the area of ??one square centimeter of material. Microcrystalline cube corner formed by the lower body after sealing an air layer, so that total internal reflection of incident light is formed, so that no metal reflective layer can be achieved by means of the most excellent reflective effect. Brightness diamond grade reflective film is more than six times the project level, strength level is more than three times. 3M body reflective stickers made security products, in a certain light source can produce a strong reflection effect, provide the most effective and reliable security for pedestrians in the dark or night workers. Reflective stickers is the use of optics, light can retroreflective Back PVC film a special structure at the light source. Weathering good performance by the thin film layer, layer of tiny glass beads Dongguan fire extinguisher boxes, focusing layer, a reflective layer, an adhesive layer and a glass layer. Fire extinguisher box, Zhaoqing fire extinguisher boxes, ultra-fire provided by the Dongguan City, South City Super Fire Department equipment operators. Dongguan Nancheng Super Fire Department equipment operators (www.jyfire.com) strong, credible, in Dongguan, Guangdong extinguishing equipment and other industries has accumulated a large number of loyal customers.
