Glass Beads of size 710 microns and below are being used as a reinforcement filler in the plastic industry. Depending on the job, bigger sizes are also being used. Spherical shape gives better stress patterns than the irregular shaped particles conventionally used. Glass beads are easily and uniform

Retroreflectivity refers to the part of incident light from headlights of a vehicle being reflected back to the driver. Retroreflectivity is normally achieved in road marking materials by using glass beads or ceramic beads.AdvertisementsThese beads are sprayed on the marking materials when the road

Usually, the glass beads used in road markings have a refractive index ranging between 1.5 and 1.9. They are developed in a wide range of sizes from 100 to 1500 microns in diameter and with different degrees of roundness. During production, glass beads can be combined into the road marking material

When a beam of light falls on a single layer of Glass Beads embedded in a Reflective or Opaque Medium such as lacquer or pointed surface it is reflected back with a brilliant glare less glow during day and at night thereby increasing the visibility. Each beads acts like a lens or prism the incident

GRINDING AND DISPERSING MEDIA :Glass beads are the main points of contact where energy from the mill is transferred to the pigment particles, causing reduction in their size. Since the Glass beads are the actual perpetrators of attrition on the pigment particles, by increasing the number of beads or

Four situations that require the addition of glass beads to road paint (Drop On)When you are planning the purchase of glass beads for your road marking projects, one of the big questions is how many tons or kilograms to buy. As our experience in past 15 years, The determining factor is where and whe
