Reflective Sheeting

Analysis on the competition pattern and market size of  prismatic reflective film market Why do micro prisms have advantages? Prismatic reflective film is a reflective film made using micro prismatic technology. Unlike microbeads reflective film, which uses glass microbeads as retroreflective units, prismatic reflective sheeting uses fine-sized polyhedral prism structures as retroreflective units. Its reflection principle is to use the refraction and retroreflection of the microprism structure to achieve retroreflection. Prismatic reflective film is produced with a microprism structure as the reflective unit has good performance in visible distance, observable angle, reflective intensity, and weather resistance. Its manufacturing technology involves multidisciplinary and high-tech fields such as materials science, optics, and precision machinery manufacturing. Prismatic reflective sheeting has been developed since the 1980s. After many updates and iterations, the product performance has been continuously improved. For a long time, domestic prismatic reflective film was completely dependent on imports. The reality has led to an increase in the demand for micro prisms: The increase in highway mileage has led to an increase in the number of highway signs and signs. The annual demand for reflective film for highway signs and signs of all levels mainly includes two types: renewal demand and new demand. At present, the average service life of reflective film for highway signs and signs in my country is about 3-7 years, so there is a considerable and continuous demand for renewal every year. For motor vehicle drivers, traveling at night is a difficult task. There are high risks on the roadside and level intersections along the road. Reflective materials can enable drivers to accurately identify road traffic environment information and risk status at night, improving the safety of night driving. Why do highways need to use micro-prisms? High-grade highways are generally trunk roads connecting political and economic centers or large industrial and mining areas. Since prismatic reflective film has the characteristics of high reflective brightness compared to micro-bead reflective film, it is mainly used in products with special requirements for reflective brightness. According to GB50688-2011 "Urban Road Traffic Facilities Design Specifications", the signs of urban expressways and urban trunk roads should use Class II-IV reflective film, and Class III or above reflective film should be used in curved sections or other dangerous sections. Prismatic reflective sheeting is different from micro-bead reflective film. It is mainly used in the signs and signs of some urban expressways, urban trunk roads and high-grade highways such as highways. According to the relevant national requirements for the setting of highway signs and signs, the average amount of reflective film used on highways is 50 square meters/kilometer, and the average amount of reflective film used on high-grade highways of level 2 (including level 2) and above is 30 square meters/kilometer. The number of high-grade highways in my country in 2020 has increased compared to 2019, and the market demand for prismatic reflective film has increased to a certain extent. How will micro-prisms develop in the future? At present, prismatic reflective films are developing towards [...]

With the rapid development of society and technologies, traffic, costumes and billboards and other fields have a great increasing demand for the prismatic reflective material. However,the Chinese manufacturer doesn’t attain the crucial technologies because of the difficulties to produce and their small size. With the target of bridging the gap of technologies between China and other aboard markets,it is the time to research the structure of prismatic reflective material’s optical function and processing. Let’s focus on the following paragraph about the way to research the prismatic reflective material.

The color and clarity of the reflective film of ordinary signs will fade after long-term exposure to wind and sun, affecting the safety of drivers driving at night. The newly replaced micro-prismatic structure super-strong reflective film meets the requirements of the new national standard and can be used for permanent traffic signs, work area facilities and contour marks. It is waterproof, sun-proof, high-definition and durable, and can better play a role in safety warning and guidance, improve the safety of drivers and passengers on highways at night and in special weather conditions, effectively reduce traffic accidents, and improve driving safety factors.

Anti-reflection film is also called anti-reflection film. Its main function is to reduce or eliminate the reflected light from optical surfaces such as lenses, prisms, and plane mirrors, thereby increasing the light transmittance of these components and reducing or eliminating the stray light of the system.

Reflective film is a kind of retro-reflective raw material that has been made into plastic film and can be directly used. The technology of reflective materials is developing rapidly. The technology of my country's reflective material industry is gradually improving and innovating, which plays a positive role in promoting the technological development of the entire domestic reflective material industry.

Prismatic reflective film is based on the principle of thin lens imaging. Glass beads are evenly embedded in organic resin on one side as an optical original, and then laminated with epoxy resin to form a glass film.

The base film of highway traffic signs 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.

Prismatic reflective film is made by hot pressing, which first uses microprisms and substrates to press into reflective film, and then coats it with a layer of metal aluminum. However, when the hot pressed pyramids are affected by external factors such as extrusion, weather changes, and water washing, they are easily damaged and deformed, resulting in a significant decrease in reflective function, so this article introduces a new technology attempt.

The choice of traffic sign reflective film should be based on the surface scratches, whether the edge is deformed, whether the color is consistent, etc. In the process of film pasting, cleaning and washing products need to be paid attention to, or choose an excellent position to see whether the film is pasted correctly.

Prismatic reflective film is different from micro-bead reflective film. It is mainly used in signs and signs of some urban expressways, urban trunk roads, highways and other high-grade roads. Due to the needs of infrastructure construction, this product is widely demanded.
