A beginner’s guide to retroreflective materials

Retroreflective materials play an important role in ensuring a safe environment for motorists and pedestrians. Also referred to as reflective materials, they work by reflecting the light back to the original source. High-visibility clothing, roads services and equipment all make use of retroreflective materials.

High-visibility ensures people and animals are seen clearly

High-visibility materials help a person, animal or object to visually stand out. Retroreflective material is an essential component of high-visibility clothing, with the tape used allowing the reflection of light through the bead technology. Microscopic glass beads can increase the brightness of reflective tape. These glass beads measure different diameters and are distributed across the surface, which is usually a textile layer. The beads are attached by an adhesive layer, which creates a mirror around the part of the bead embedded into the material.

How well the tape performs is determined by a number of factors, including the size of the beads and how spherical they are. Their performance is also dependent upon the distribution across the surface of the textile and the depth of the beads.

Strength of material will affect the durability

How long the reflective nature lasts will depend on how well the beads have been embedded into the tape. The flexibility of the adhesive layer will also have a bearing upon performance, with the strength of the material also playing a part in the durability. Any loss of beads will cause the effectiveness to decrease.

Chapter 8 chevrons also enable high-visibility

Safety is key, with Chapter 8 chevrons or high-visibility markings required for highway vehicles. These should adhere to specifications laid out in the Government Traffic Signs Manual. Quality, self-adhesive markings for the full spectrum of vehicles can be obtained from a variety of suppliers, such as https://www.vehiclechevrons.com/.

According to Science Daily, new retroreflective material could be used in night-time colour-changing road signs. The technology that would improve safety for motorists and pedestrians could also help to focus attention on important traffic information when it is dark.

Reflective material is made up of layers including a protective film, a reflection layer, a base, an adhesive layer, and a protective bottom layer.

Reflective film can be categorised as embedded reflective film, sealed reflective film, EGP (engineer grade prismatic) reflective film, and HIP (high-intensity prismatic) reflective film.
