SWARCO Standard Glass Bead Products

SWARCO minireflectors with a refractive index of 1.5

Throughout the world, roads are much safer today due to the use of small, spherically shaped glass beads which are added to the freshly striped highway lines as they are applied. Only with glass beads the markings become visible at night. This phenomenon is called retroreflection. SWARCO has been manufacturing highly retroreflective glass beads for almost 40 years now. ISO 9001:2008-certified production processes and pure raw materials ensure that SWARCO glass microspheres are very consistent with regard to their chemical and physical properties.
