High Intenstity Micro-prismatic (HIM) 94000 series sheeting is a high intensity un-metallized micro-prismatic retro-reflective sheeting designed for production of permanent traffic control signs, construction zone devices and delineators. HIM 94000 series conforms to ASTM D4956-09 Type IV specifications, and is embedded with the logo – HIM for easy identification.
HIM Grade is a retro-reflective sheeting that uses the principle of the retro-reflection of micro-prisms. In the case of a prism-type reflection element, the light reflects 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.
