Engineering grade reflective film: Engineering grade reflective film belongs to the Chinese standard document of Class I reflective film, the reflectivity cannot be lower than 70 light. It is made of PMMA acrylic and has an internal reflective structure of micro rhombus mirror, with an outdoor weather resistance of 7 years. It is also known in the industry as EGP reflective film because of its EGP logo. However, there are also non-standard products in the industry called flat engineering grade reflective film, which is made of PET or PMMA material with an internal reflective structure of implanted glass beads, some of which can reach the national standard of one type of reflective film, while others cannot reach the standard of one type of reflective film and are relatively cheap. These are described separately below.
Common brands include 3M, TD, DINGFEI, Avery and Oreflex. All of the above are made of PMMA and have a reflective structure of micro-rims. The outdoor weathering performance and reflectivity meet the national standards. 3M and Anyuan engineering grade reflective films have the EGP logo on the surface. The regular colours of reflective film are: white, red, blue, yellow, green and more. Usually used for: road traffic signs, national highway traffic signs, road crossings, warning pillars and other deep processing. The price of engineering grade reflective film is 58 RMB - 68 RMB/M², with imported products generally having a high price.
Flat engineering grade reflective film is made from PET or PMMA, the quality of which varies from manufacturer to manufacturer due to inconsistent production levels and technology. However, the reflective structure is all glass beads, so the appearance of flat process grade reflective film is basically indistinguishable from advertising grade reflective film, the biggest difference being the brightness of the reflective light and its service life. The most important difference is the brightness of the reflective film and its service life. Currently, the service life of flat engineering grade reflective film on the market is between 3-7 years and the brightness of the reflective film is between 30-70. Flat engineering grade reflective film is usually used in some rural road traffic signs, warning pillars, road junctions and some low end traffic facilities such as car stoppers. Flat engineering grade reflective film is available in the range of 16 - 30 RMB/M².
In summary, there are two types of engineering grade reflective film and there is a very simple way to clearly state what you want to buy when you need it. You can tell the manufacturer that I need EGP reflective film or national standard engineering grade reflective film if you need to buy flat reflective film then you can just say that you need to buy flat engineering grade reflective film. You can refer to the prices above.
