ANS' heat transfer reflective trim is converted from self developed high performance reflective materials. It is formed of a plurality of separate but closely spaced trim segments in a generally repetitive pattern continuous for the length of the trim. The trim segments are formed of a retroreflective material that has a retroreflective coefficient or index value(Ra).

The trim consisting of the combined retroreflective segment and non-segment areas has a composite retroreflective index (Rb) that is less than that of the retroreflective materials alone(Ra), the reduction relationship is linear. For example, if the retroreflective segment area of the trim constitutes 75 % of total trim area, the retroreflectivity of the trim will  be 75 % of that of the retroreflective materials,  Rb = Ra x 75% .  if Rb meets the minimum retroreflectivity criteria listed in the EN IS0 20471 or ANSI/ISEA 107 standard, then the trim pass the standards also if the retroreflective materials pass.

When measured at 0°orientation,5°entrance angle and 0.2°observation angle, the retroreflectivity Ra of reflective materials used on ANS' is more than 500 cd/lux/m², the space cut out on ANS' trim is less than 20% and remains more than 80% segment retroreflective materials. Therefore, the retroreflectivity Rb of ANS' heat transfer reflective trim will be more than 400 cd/lux/m² (500 x 80%), which pass the minimum retroreflectivity criteria of 330 cd/lux/m² in both EN IS0 20471 or ANSI/ISEA 107.
