High Performance Screen Materials Glass Microspheres

High Performance Screen Materials Glass Microspheres Bead properties that are controlled during the manufacturing process include those that are chemical and physical in nature. The chemical and physical properties of beads have a major influence on how well the beads reflect light. These properties include: bead size, refractive index, clarity, roundness. High Performance Screen Glass Microspheres Bead Size The size of a glass bead can affect retroreflectivity, especially under wet conditions. Larger beads have slightly higher retroreflectivity than standard beads under dry conditions. Note that bead size has no effect on refractive index.When markings are wet, beads are often rendered useless because the film of water that covers the marking causes light to scatter before it can enter the bead. This causes the wet markings to be nearly invisible at night. Large beads may be more effective when roads are slightly wet because their higher profile protrudes through the…
