[edit] Characteristics
Retroglo is made up of 50, 000 minute glass beads in each square inch. The material reflects light directly back to a light source, such as a car's headlights. Retroglo can be woven, braided or knit into fabrics or into trim to be applied to fabric.[2]
[edit] Construction
3M Scotchlite Reflective Material is laminated in wide rolls on either one or both sides of a polyester film. The wide rolls are slit to narrow widths to make Retroglo yarns which have a rectangular cross section. The width, which has the retro reflective surface, is always wider than the thickness with standard widths of 1/69", 1/32",and 1/23". The breaking strength of Retroglo is 250 grams and yield point is 15-20 grams.[3]
