Reflective film, is a novel reflecting material with special process combines reflection layer and PVC, PU and other high molecular material formed by glass beads and the formation of the.
Reflective film understanding is a film class can reflect light from literal. 3M reflective film is widely used in automobile body reflective stickers, this is the most common, is also a kind of automobile safety marks, ensure traffic safety to reduce the reflective material accidents. On the car of the great role in the night reflection film.
Function
The main function of auto body reflective stickers are the unique properties of reflective material the use of reflective film, to light projection direction reflection light. The purpose is to exercise each direction of automobile at night when the driver could be the first time to pay attention to the existence of the car. Ultimately improve driving safety coefficient. Reflective paste materials used are of many types: type PET, acrylic type, simple is plastic, with water-proof function
. High quality reflective film on the reflective definition at night should be more than 6m, and poor quality film will be foggy feeling. Now reflecting brightness 3M reflecting film is 6 times than traditional identity. During the day, the logo can appear bright white; in the evening, mark for reflecting the effect of super. You can also play a role of diaphragm isolation UV, UV isolation layer, is high pressure chemical plating monolayer.

3 structure and color classification
The light reflecting layer, a bottom film, pressure sensitive adhesive and a release layer, the main color: white, red, blue, yellow, green, orange, fluorescent yellow, brown and so on more than ten kinds of color and light green, purple, lavender, fluorescent yellow and other special colors.
4 use
Safety protection products made of reflective material, reflective effect can produce strong in the light irradiation is certain, provide security the most efficient and reliable for the pedestrian in the dark or night workers.
3M reflective film is the use of optical principles, can light retroreflective back to PVC film with a special structure of light source. By thin layer good weathering performance, micro glass bead layer, focusing layer, the reflective layer, adhesive layer and the release layer composed of.
5 quality identification
The main quality differential point 3M reflective film: film material, the Pearl rate reflecting coefficient of glass beads, beads, death rate, color uniformity, weather resistance, adhesive viscosity.
The 6 reflective identification
Reflective materials for industry mainly refers to various kinds of reflective film five levels, diamond grade reflective film, high-strength reflecting film, engineering grade reflective film, advertising reverse
Optical film and plate reflective film etc.. Mainly used for the production of all kinds of reflective signs, vehicle license plate, safety facilities, with its bright colors play a warning role is obvious in the daytime, at night or in low light conditions, the effect of reflective bright can effectively enhance people's ability to identify, to see the target, causing alarm to avoid accidents., to reduce casualties, reduce economic losses, as security guards road traffic indispensable, has obvious social benefit.
