ASTM D4956 Type 1 “Flexible” Engineer Grade Reflective Graphics film is a unique version of EG made by Nikkalite. It is very similar to standard Type 1 engineer, only more conformable. It performs like standard EG when at a room temperature, but when warmed, it softens and becomes more moldable. Flexible engineer grade is thin, easily CAD cuttable, made in a single layer, flexible, and stretchable when warm. Once applied, it performs just like any other engineer grade film. To the best of my knowledge, Flexible Engineer Grade is available in the most colors of any reflective film. A specifications sheet for Type 1 “Flexible” Engineer Grade is below –
