What are the grades of reflective sheeting?
- May 18, 2018 -


Grades of reflective sheeting are divided into: diamond grade, crystal grade, super intensity grade, high intensity grade, super engineering grade, engineering grade, economic grade.


Economic grade reflective sheeting (advertising, commercial grade)


The reflective principle of this series of reflective film is the same as the engineering grade.

Engineering grade reflective film


The performance of this series of reflective film belongs to the fourth grade reflective film of JT-T279-1995 standard issued by the Ministry of Communications of the People's Republic of China. It is a durable sealed reflective film. This material has been successfully used to make traffic signs since the early 1950s. At present, engineering-grade reflective films still have certain applications in areas with small traffic and low-velocity vehicles.


Engineering-grade reflective film is suitable for traffic signs on general roads, that is, the usual primary, secondary, tertiary, and fourth-grade roads and signs for temporary use. Generally divided into pressure-sensitive and thermal type two. Using the same type of ink, various patterns can be made using screen printing technology.


Uses: Guide signs; prohibition signs, warning signs and indication signs, and signs used in ordinary advertising.


Lifetime:

Generally 3 to 7 years, depending on the manufacturer. Some manufacturers only provide 7 year retroreflective film, and the brightness retention after 7 years is at least 50% of the initial brightness value. Some manufacturers provide 5 years and 7 years of reflective film.Topmatched Enterprise Limited provides five types of engineering-grade reflective films for five years: PET, 5-year acrylic, and 7-year acrylic.


Applicable base plate: Aluminum plate, steel plate.


Operating temperature: General requirements at 18 °C ~ 28 °C.


High intensity grade reflective sheeting


The performance of this series of reflective sheeting belongs to the third grade reflective sheeting of JT-T279-1995 standard issued by the Ministry of Communications of the People's Republic of China. High-strength grade reflective film is a durable sealed reflective film, which is at least three times brighter than the engineering-grade reflective film. The material has been successfully used to make traffic signs. Even if the sign is in a larger angle and in a bright area, the high-strength reflective film makes the sign clearly visible, effectively predicting the danger of the road in front of the driver.


High intensity grade reflective film is suitable for traffic signs on general roads, that is, the usual expressways, first class, second class, third class, fourth class roads and temporary use signs. Generally divided into pressure-sensitive and thermal type two. Using the same type of ink, various patterns can be made using screen printing technology. 


Uses: Guide signs; prohibition signs, warning signs and indication signs, and signs used in ordinary advertising.


Lifetime: Generally 10 years, under normal use, this series of reflective film will have a brightness retention value of at least 80% of the initial brightness value after 10 years.

Applicable base plate: Aluminum plate, steel plate.


Operating temperature: General requirements at 18 °C ~ 28 °C.


Diamond grade reflective sheeting


The performance of this series of reflective film belongs to the first and second grade reflective film of JT-T279-1995 standard issued by the Ministry of Communications of the People's Republic of China. Its reflective principle is different from the principle of glass bead used in engineering grade and high-strength grade reflective film. Instead, it uses the latest technology in crystallite cube reflection.


Each crystallite cube of the diamond grade retroreflective film is arranged to have more than 930 microcubes in one square centimeter of material. The lower layer of the microcrystalline cube corner body is sealed to form an air layer, so that the incident light forms internal total reflection, so that the most superior light reflection effect can be achieved without using a metal reflective layer. Compared with the traditional engineering grade and high intensity grade reflective film, the reflective grade of diamond-grade reflective film made of wear-resisting high-hardness polycarbonate material and microcrystal cube technology not only doubles, but also has wide-angle performance. improve. The brightness of the diamond grade reflective film is more than six times that of the engineering grade and three times that of the high grade.


Applicable to traffic signs on high-grade highways and urban roads. Under normal use conditions, the brightness retention after 10 years is at least 50% of the initial brightness value. Using the same type of ink, various patterns can be made using screen printing technology.


Uses: Guide signs; prohibition signs, warning signs and indication signs, and signs used in ordinary advertising.


Lifetime: Generally 10 years, under normal use, this series of reflective film has a brightness retention value of at least 50% of the initial brightness value after 10 years.


Applicable base plate: Aluminum plate, steel plate.


Operating temperature: General requirements at 18 °C ~ 28 °C.
