The products of reflective materials industry mainly involve road signs, vehicle license plates and body reflective signs, occupational protection and other fields. In view of the particularity and professionalism of downstream industries, customers have high requirements on the comprehensive strength of suppliers in this industry, especially the stability of product quality. Therefore, there is a high industry threshold for entering the industry.

(1) there are still some differences in the level of equipment development at home and abroad. Some important or core equipment still need to be imported. At the same time, different products need to be equipped with a variety of different equipment, so the investment in production equipment is large. The industry's downstream customers involve a wide range of products, which requires the industry's production enterprises to have sustained product R & D investment capacity, which forms a capital barrier for new entrants with weak capital scale. With the development of domestic reflective material industry, the essence of industry competition is gradually entering the competition of production scale and product differentiation. In the background of fierce market competition, the anti risk ability and scale advantage of leading enterprises are gradually highlighted, and the market share will be further concentrated.

(2) technical barriers the industry has a high demand for talents, which not only needs talents who are proficient in professional knowledge, but also needs interdisciplinary knowledge background and rich practical experience. From the perspective of product production, the professional knowledge involved in the development and production of reflective materials covers many disciplines, such as physical optics, polymer materials science, chemistry, mechanical equipment manufacturing, etc., with a large span and strong specialty. The raw materials used for reflective materials include inorganic products such as glass beads, acrylic resin, polyester resin, chlorine acetate resin, PMMA, PC, organic solvents and other complex organic products. The materials are independent and related. In the production of products, the formula and process are highly complex, and it takes years of exploration and accumulation to produce molded and stable products. For the new entrants who lack technology and talent accumulation, technical barriers are higher. For the development of reflective film, reflective cloth and fine reflective products in the reflective material industry, the process is more difficult. Therefore, for any enterprise that wants to enter the industry, it will cause huge technical barriers.
