Product description
High refractive index airport glass beads are also called all weather reflective glass beads. The products which upgraded from former ordinary glass beads and used in road marking,especial in airport runway, improve considerably the level of road safety. It makes up deficiencies of ordinary road marking to continue reflecting with luminous effects so that helps motorists to follow their respective lanes and ensures driving safety and no accident even in raining night. High refractive index glass beads are the ordinary glass beads’ update product which are used in the reflective system of highway, mountain road, city road and airport runway. Compared with ordinary glass beads, High refractive index airport glass beads have the distinction as below: 1. Perfect and reasonable optical design helps the products possess all-weather reflective performance. 2. Unique and distinct optical system ensures that the road marking keeps reflecting light in sunny, rainy day and damp weather. 3. Long retroreflecting distance can content the maximum distance which the drivers require. 4. The products which use special optical materials and processing techniques have stable and lasting reflective performance. It applies to various types of painting and marking machines which not need any modifications. 5. There are specialized colors of glass beads used for corresponding .White and yellow marking lines to ensure that the glass beads can reflect the same color light as the marking lines and avoid the appearance of yellow marking lines looked white in distance at night. Colorful All weather reflective glass beads can help the drivers to identify the marking lines’ color easily and strengthen safety warning function of different color marking lines.
