What are the reflective films commonly used on roads?
Super-strong reflective film:
High-speed traffic sign base film generally uses super-strong reflective film. Compared with diamond-grade reflective film, super-strong reflective film is more affordable. At the same time, the service life of super-strong reflective film can also meet the use requirements of high-speed reflective film.
Super-strong reflective film is generally called Class 4 reflective film and Class 2 reflective film in the market. Class 2 reflective film is super-strong reflective film and Class 4 reflective film. The old national standard is called Class 2 reflective film, and the new national standard is called Class 4 reflective film. Generally, you will see what level of reflective film is required to be used in the bidding documents. The common one is: the use requirement of reflective film is the national standard Class 2 reflective film, which is super-strong reflective film.
Introduction to super-strong reflective film and diamond-grade reflective film:
The functions of these two series of reflective films belong to the second and first-level reflective films. Their reflective principles are different from the glass bead reflection used in engineering-grade and high-strength reflective films. These two reflective films use the latest technology of microcrystalline cube reflection. After each microcrystalline cube is placed together, there will be more than 930 microcrystalline cube corners on each square centimeter of material area. After sealing, an air layer is formed, so that the incident light forms internal total reflection, and then the best reflective effect can be achieved without relying on the metal reflective layer. The service life is generally 10 years.
Super-strong reflective film production:
Super-strong prismatic reflective film has a micro-cube retro-reflective structure with a closed layer. It is made of a polymer resin with special aging resistance. Its reflection system consists of sealed air-reflective microprism units.
