Back adhesive rubber magnetic strips are professional flexible magnetic accessories developed for advertising sign fixing, display board pasting, publicity banner fixation and commercial display assembly. Made of high-quality rubber soft magnetic materials with high-viscosity back glue integrated processing, the product has the dual advantages of flexible magnet adsorption and self-adhesive fixed pasting, solving the problems of difficult fixation, easy falling off, inconvenient disassembly and damage to the wall of traditional advertising signs. Rubber magnetic strips have good flexibility, toughness and ductility, can be bent arbitrarily according to the installation radian of advertising signs, adapt to flat, curved and irregular installation surfaces, and are suitable for various material sign boards such as acrylic, PVC, metal and paper. The integrated back adhesive design adopts high-quality environmental protection pressure-sensitive adhesive, which has strong viscosity, firm pasting, no degumming at normal temperature, and can be perfectly bonded with smooth surfaces such as wall surfaces, glass, metal plates and display racks. When disassembled and replaced, it can be peeled off tracelessly without residual glue, no damage to the installation base surface, avoiding the wall paint falling off and surface scratches caused by traditional glue and screw fixation. In terms of magnetic performance, the magnetic strip has uniform and stable magnetic force, strong adsorption and matching performance, and can be used in pairs with iron-based metal substrates to realize fast positioning and fixed assembly of advertising signs. It supports repeated disassembly and reuse, which is very suitable for frequent replacement of promotional posters, activity signs and display boards in commercial scenarios such as shopping malls, supermarkets, stores and exhibition halls. The product has complete specifications, including different widths, thicknesses and lengths, and can be cut arbitrarily according to the size of advertising signs, realizing flexible matching of small signs and large display boards. The surface of the magnetic strip is smooth and flat, with good wear resistance, anti-oxidation and anti-aging performance, not easy to fade and deform after long-term indoor and outdoor use, and can adapt to conventional temperature and humidity changes in commercial environments. Compared with traditional fixing methods such as screws, rivets and glass glue, back adhesive rubber magnetic strips have the advantages of fast installation, no construction damage, reusable use, low comprehensive cost and beautiful overall effect, which greatly improves the installation efficiency of advertising signs and optimizes the display effect of commercial publicity. In addition, the product is safe and environmentally friendly, odorless, and complies with commercial environmental protection standards, suitable for long-term use in indoor business spaces, office environments and exhibition venues. It is widely used for fixed pasting of advertising posters, promotional signs, directory signs, display boards, mall guide signs and exhibition display banners, and is an essential efficient and convenient fixed accessory for the modern advertising and display industry.
