Solid Glass Microspheres, also called glass beads, provide multiple benefits including enhanced processing, excellent chemical and heat resistance, thermal stability, low oil absorption, and are often used in automotive, electrical, household appliance, adhesives, packaging, paint and construction industries. Glass is non-toxic, extremely stable and recyclable. Cospheric specializes in solid glass microspheres with perfect sphericity, tight tolerances and particle size distributions for biomedical, life sciences, microscopy, automotive, high-tech equipment and specialty applications. view less | |

PMMA microbeads are known for high impact and heat resistance, and good tensile and flexural strength. These strong yet lightweight polymer microspheres are often used as spacers, fillers, and reference particles for a variety of specialty applications in life sciences, medical technology, MEMS, optics and development of high performance composites. Uncoated poly(methyl methacrylate) or PMMA microspheres and spheres are often used in manufacturing of porous ceramics, self assembled microfluidic devices, and in biomedical research. Also often used as a lightweight alternative to glass microspheres. view less | |

In bulk, these metallized glass spheres appear as a grey powder. Under an optical microscope, each individual microsphere displays a partial aluminum coating. Aluminum (Al) coatings on microspheres offer advantages in developing retroreflective surfaces for high visibility materials and applications. The hemispherical (half-shell) aluminum coating creates the mechanism for retroreflectivity as the light passes through the clear half of the glass bead and “bounces” off the reflective aluminum-coated back surface, directing the light back to the source or the viewer. Additional surface coatings (silane or fluorochemical) ensure that the spheres remain on the surface of the formulation, thereby enhancing the effect of retroreflectivity. view less |
