Crystal Grade Reflective Sheeting – available at www.signsheeting.com
Crystal Grade (CRG) is Nikkalite’s brightest film. It is a very bright and very tough Type 8 film. Characterized by a modified octagon pattern. This is an acrylic based film that uses air backed prismatic technology for reflection. 10 year outdoor life. Comparable to diamond grade material.
The values shown below are average typical values determined by our own measurement method using the entrance angle and with the arrow marks of the CW types indicating the directions parallel to the observation angle.
Brightness after ink printing and affixing overlay films
When Nikkalite® inks or the PA100 series overlay films are applied to the white sheets of CRG 92002, the reflection performance of the corresponding colors at an observation angle of 0.2 degrees and an entrance angle -4 or 5 degrees can be expected to be greater than 70% of the values shown in Table 2.
Crystal Grade is “Super High Intensity” microprismatic sheeting, meeting the requirements of ASTM D 4956, Type VIII. Crystal Grade has the highest retro-reflectivity characteristics at long and medium road distances. This product is ideal for highway signing, construction zone devices, and delineators.
Crystal Grade uses micro-prisms for efficient retro-reflectivity. In the case of a prism-type reflection element, the light reflects s efficiently without diminishing, as the three reflection planes that constitute the element and are positioned at right angles in relation to each other, completely reflect within the element. As the specialty prisms designed to provide optimum reflection are densely arranged within the sheeting, excellent brightness characteristics and wide-angle reflection can be obtained. The traffic signs and traffic safety devices made of the reflective sheeting provide far better visibility and withstand a longer service period compared with those that utilize glass beads
