The Oralite 5500 Engineer Grade is a weather resistant reflecting film that is primarily used for manufacturing traffic control, guidance, warning and information signs. The surface is retroreflective – which means that light falling on the film will be reflected back in exactly the same direction from whence it came; i.e., it will not be diffused and reflected out in all directions. In this way, the light is reflected in a more narrow angle and is consequently much brighter. We offer for sale this reflecting material with a width of 615 mm and also reworked as an adhesive tape with a width of 25 mm.
The special reflecting attributes of this film comes about as a result of catadioptric glass beads being embedded in a transparent layer of plastic material. The multi-layered construction of the film is protected by a cast resin, scratch-resistant surface layer.
In addition to its ability to serve as a warning system it can also be nicely used for nocturnal decorations and lettering. The red colour is of course easily imagined in its luminescence - the black, however, is very noteworthy as well: it shines with a kind of milky appearance and has a rather anthracite colouring, the result being that it produces a surprising and very special effect.
Processing: This adhesive material can be cleanly cut with a plotter and printed on by means of a screen printing process. Comprehensive instructions for working with this material can be found at the Orafol website: www.orafol.com
This film will adhere to wood, glass, plastic, metal, porcelain, leather and, conditionally, to other materials as long as they do not have to be washed or cleaned sometime in the future. The intended substrate must be clean, dry and free of grease or fat.
The reflecting values of the Oralite 5500 conform to the relevant national specifications covering reflective materials found in the official regulations: EN 12899-1 (Europe), DIN 67520 und DIN 6171 (Germany), BS 873: Part 6 (Great Britain), NFP 98-520 (France), SN 640878 (Schwitzerland), ASTMD 4956 (USA) und JIS Z 9117 (Japan).
According to the manufacturer, the Oralite 5500 Engineer Grade is weather resistant for up to 7 years when in a vertical position in normal Middle European weather conditions. In addition, this film is resistant to salt water, most mineral oils, fat and grease, fuels, aliphatic solvents, weak acids, salts and alkaloids.
