What is prismatic reflective tape?

Microprism structure refers to many tiny prisms arranged on the surface of a material, which can reflect light. This structure may be more efficient than ordinary reflective materials because each prism can reflect light multiple times, increasing the reflective effect.

Prism reflective tape is an efficient reflective material widely used in fields such as traffic safety, personal protection, and industrial signage. The following are its core points:



1. Structure and Materials
Microprism technology: The surface is covered with tiny prisms (usually triangles or hexagons), which are precisely arranged to form efficient reflective structures.
Material: High weather resistant engineering plastics (such as PC, PMMA) or flexible substrates (such as PET film) are often used to ensure long-term outdoor use.



2. Reflection principle
Ray path: After multiple refractions and total reflections by a prism, the incident light returns to the direction of the light source along its original path, forming a "retroreflection" effect.
Wide angle reflection: Prism design optimizes the capture of light at different angles, effectively reflecting even when light comes from the side (such as when the vehicle headlights are slanted).

3. Performance advantages
Ultra high brightness: The reflection intensity can reach more than 5 times that of ordinary glass bead materials, and the visible distance at night exceeds 500 meters.
Wide angle: The effective reflection angle can reach ± 60 °, suitable for complex scenes such as bends and intersections.
Durability: The UV resistant coating provides a lifespan of 7-10 years and can withstand extreme temperatures ranging from -40 ℃ to 80 ℃.



4. Core applications
Traffic engineering: highway markings, tunnel reflective signs, traffic cones.
Vehicle safety: side protection strips for trucks, high visibility markings for new energy vehicles
Personal protection: Firefighter combat suit (EN469 standard), railway engineering vest (ISO20471 Class III)
Special fields: aviation obstacle light identification, reflective strips for marine rescue equipment



This material, designed with precision optics, can enable warning signs to be recognized 10-15 seconds in advance in hazy weather with visibility below 100 meters, significantly reducing the accident rate. With the development of autonomous driving technology, its role as a benchmark for machine vision recognition is becoming increasingly prominent.
