We all know that reflective materials mainly include reflective film, reflective tape, reflective yarn, reflective clothing, reflective piping, reflective cloth, etc. The reflective effect of reflective material is mainly because the reflective material contains a kind of high refractive index glass beads. Because of its existence, the incident light is reflected back to the light source, forming a back reflection phenomenon.

The reflective material is glass beads, which are made using the principle of directional regression of light refraction. Warning signs and clothing accessories made of reflective materials are hundreds of times more prominent than other non-reflective materials. The gray reflective material with a diameter of half a meter is illuminated by the headlights of the car, allowing the driver to see the target within 800 meters.

Now the reflective material market is expanding. Product application fields are becoming wider and wider, and specialization is becoming more and more refined. Corresponding international standards have also been developed for reflective materials for different purposes. For example, the international professional standard EN471. Companies and countries have increasingly strict regulations and extensive promotion on the use of reflective materials. For example, in the case of bad weather, the elderly and children can choose to wear or wear reflective signs or clothes when going out to make the clothes beautiful and practical, and increase safety functions.
