What are the three main categories of reflective film? What are the characteristics of each?

The safety protection articles made of reflective materials can produce strong reflective effects under certain light sources, providing the most effective and reliable security for pedestrians or night workers in the dark.

Reflective film is the use of optical principles, can reflect the light back to the light source of a special structure of PVC film. It is composed of thin film layer, tiny glass bead layer, focusing layer, reflection layer, viscose layer and peeling layer.

The main quality identification point of the reflective film: the material of the film, the reflection coefficient of the glass bead, the cloth bead rate, the dead bead rate, the average color degree, weather resistance, viscose layer viscosity, etc.

The level of reflective film is divided into: diamond level, high strength level, engineering level, economic level.

Reflective film is mainly used for all kinds of road and railway guide plate, indicator, mine airport safety plate, stage set, trademark, name brand, license plate, etc.

Engineering grade reflective film

The function of this series of reflective film belongs to the Ministry of Communications of the People's Republic of China JT-T279-1995 scale fourth grade reflective film, is a durable sealed reflective film. The material has been used successfully to make traffic signs since the early 1950s. At present, the engineering grade reflective film still has a certain application in the areas with small traffic flow and low speed of motor vehicles.

Engineering grade reflective film is used for traffic signs of general roads, that is, the usual first, second, third, fourth grade roads and temporary use of signs. It is generally divided into two types: pressure sensitive and heat sensitive. Using the same kind of ink using screen printing technology can make all kinds of patterns.

Purpose: Guide sign; Prohibited signs, warning signs and indication signs, as well as signs used in general advertising.

Life: generally 3 ~ 7 years, according to the different manufacturers. Some manufacturers only provide reflective films for 7 years, and the brightness retention value after 7 years is at least 50% of the initial brightness value. Some manufacturers offer 3, 5, 7 years of reflective film.

Suitable base plate: aluminum plate, steel plate.

Operating temperature: generally required in 18 degrees Celsius ~ 28 degrees Celsius.

High intensity reflective film

The function of this series of reflective film belongs to the Ministry of Communications of the People's Republic of China JT-T279-1995 scale third grade reflective film, high intensity reflective film is a kind of durable sealed reflective film, at least three times brighter than the engineering grade reflective film. The material has been used successfully to make traffic signs. Even if the sign is at a large Angle and in bright areas, the high-intensity reflective film makes the sign clearly visible and effectively predicts the dangerous situation of the road ahead of the driver.

High-intensity reflective film is used for traffic signs of general roads, that is, the usual highways, first class, second class, third class, fourth class roads and temporary use of signs. It is generally divided into two types: pressure sensitive and heat sensitive. Using the same kind of ink using screen printing technology can make all kinds of patterns.

Purpose: Guide sign; Prohibited signs, warning signs and indication signs, as well as signs used in general advertising.

Life: generally 10 years, the series of reflective film in normal use, 10 years after the brightness retention value of at least 80% of the initial brightness value. Suitable base plate: aluminum plate, steel plate.

Operating temperature: generally required in 18 degrees Celsius ~ 28 degrees Celsius.

Diamond grade reflective film

The function of this series of reflective film belongs to the Ministry of Communications of the People's Republic of China JT-T279-1995 scale of the first and second level of reflective film, its reflective principle is different from the engineering grade and high intensity level reflective film using the glass beads reflection principle, but the use of microcrystalline cube reflection of the latest technology.

After each microcrystalline cube of the diamond grade reflective film is connected and arranged, there will be more than 930 microcrystalline cube corners in a square centimeter of material area. The lower layer of the microcrystalline cubic Angle body is sealed to form an air layer, so that the incident light forms an internal total reflection, so that the best reflection effect can be achieved without the help of the metal reflection layer. The use of wear-resistant high hardness polycarbonate materials and microcrystalline cube technology made of diamond grade reflective film and the traditional engineering grade and high intensity grade reflective film compared, its reflective function not only doubled, and wide Angle function has also made great progress. The brightness of diamond grade reflective film is more than six times that of engineering grade and more than three times that of high intensity grade.

Used for traffic signs on high - grade highways and urban roads. Under normal use conditions, the brightness retention value after 10 years is at least 50% of the initial brightness value. Using the same kind of ink using screen printing technology can make all kinds of patterns.

Purpose: Guide sign; Prohibited signs, warning signs and indication signs, as well as signs used in general advertising.

Life: generally 10 years, the series of reflective film in normal use, 10 years after the brightness retention value of at least 50% of the initial brightness value. Suitable base plate: aluminum plate, steel plate.

Operating temperature: generally required in 18 degrees Celsius ~ 28 degrees Celsius.
