high quality glass beads with best price from China CAS NO.65997-17-3

reflective glass beads owns a high index retro reflective property,the principal of the micro structure reflective material is:light exposure to the object like lens, focus by refraction layer, and then go through the lens from the focal point of to the direction of the light source,form a reflective aluminum layer on the back hemisphere surface of high refractive glass beads,and then >85% of the direct light return to the light source.the retro reflective brightness that the product formed, enable drivers or outdoor workers with light source at night or low-light conditions to identify and take measures to avoid the obstacles as early as possible,so that ensuring safety.

half shell coated aluminum glass spheres,offered in partially aluminum coated

retroreflective version,are excellent for use as a functional retro reflective additive to addition

into transparent paints and coatings.half shell coated aluminum glass spheres with sizes of

about 40-80 microns mean diameter provide a small enough size for most coatings while offering

a large enough size to reflective a significant amount of light.

this glass micro spheres can be widely used in roads, ports, mining, fire and other fields. as a safety signs,

greatly improving the user's safety and reliability. half shell coated aluminum glass spheres , traffic signs, reflective materials
