Recognize 3M reflective film and its classification at different levels

3M reflective film is widely used as the reflective sticker of car body, which is common to us *, is a kind of vehicle safety sign, * and is a reflective material for traffic safety to reduce accidents.


Reflective film is literally a kind of film that can reflect light. 3M reflective film is widely used as the reflective sticker of car body, which is common to us *, is a kind of vehicle safety sign, * and is a reflective material for traffic safety to reduce accidents. Reflective film has a great effect on cars at night.


Let's first understand the function of reflective film:


The main function of auto body reflectors is to reflect light to the light source by using the unique performance of reflective materials of reflective film. The purpose is that drivers in all directions can notice the presence of the car at the first time when the car is driving at night. To achieve the ultimate goal of improving the driving safety factor. There are many types of materials used for reflective stickers: PET type, acrylic type, etc., which are generally plastic and waterproof* The reflective clarity of the reflective film at night should be more than 6m, while the poor quality film will feel foggy. Now the reflective brightness of 3M reflective film is 6 times that of traditional signs In the daytime, the sign can be bright white; At night, signs provide reflective effect. It can also play a role in isolating ultraviolet rays. The vehicle film is a single layer of high-pressure plating to isolate ultraviolet rays.


3M reflective film can be divided into the following levels:


1. Diamond VIP3990, LDP3970 series


Features: strong reflective brightness, * several times of high strength level, long service life. Diamond grade VIP reflective film is called "wide angle visibility reflective film", and diamond grade LDP reflective film is called "long straight distance visibility reflective film"


Application: traffic signs of high-grade highways.


2. The third generation diamond grade 4090 series


Features: strong reflective brightness, full angle reflection, performance *, a new product of 3M Company *.


Application: traffic signs of high-grade highways.


3. Class 3930 series


Features: prismatic reflective film, the reflective intensity is more than twice that of the advanced grade, and the service life is long.


Application: traffic control signs, prohibition signs, warning signs, indication signs, delineators, guidance signs, separation and merging signs, etc.


4. High strength 3800 series


Features: strong reflective brightness, long service life.


Application: It is applicable to traffic signs of high-grade highways and urban roads.


5. Engineering grade EG7 3200 series


Features: wide range of use


Application: applicable to traffic signs on general roads.
