High Refreactivity Micro Glass Bead For Reflective Fabric
Introduction
Glass beads are tiny spheres of glass that are used in paint and durable road markings to reflect light back to the driver in dark or poor weather conditions - improving safety and visibility. The glass beads play a very important role in the road safety .During day time the white road marking material gives the sufficient visibility as a contrast to the asphalt. In the night time contrast of the white line is not sufficient and must be improved by adding light reflective glass beads.

Quality Standard:
1. The appearance is clean, transparent and free of impurities;
2. The bubble content in the glass beads is less than 10%;
3. The magnetic particles do not exceed 0.1% of the product weight;
4. Does not contain any silicone resin ingredients;
5. Rounding rate ≥90%
Application areas:
Retro-reflective fabrics all use microbeads. Retro-reflective fabric is very important for the selection of microbeads. In order to achieve a higher reflectivity, the refractive index of the beads should be between 1.9-2.2 and the diameter should be within the range of 44-88μm. This is because the reflective fabrics processed with the beads in this range can achieve a light and soft effect. Because this product has the outstanding characteristics of high reflective intensity, good use effect and no need for external power supply, etc., high-refractive glass beads have a wide range of applications. For example: reflective fabrics, reflective coatings, chemical coatings, advertising materials, clothing materials, reflective films, reflective fabrics, reflective signs, signs, airport runways, shoes and hats, school bags, water, land and air life-saving supplies, etc.
