Neutrally Buoyant in Water – Microspheres with Specific Gravity of 1g/cc

Suspension of microspheres in water enables the visualization and characterization of fluid flow and testing the capability of devices to withstand particulate matter in the fluid stream, ensuring that microspheres do not settle and do not float on the surface. Most of these polymer microspheres are at least moderately opaque and clearly visible in water, clear or translucent…

Microspheres for Medical Devices – MDDI Magazine – January 2011

High-quality polymer microspheres are commercially available in a
wide variety of colors and with controlled fluorescence, opacity,
specific gravity, particle size distribution, and electrostatic charge,
presenting endless possibilities for use in developing and testing
medical devices. To select the right microsphere for the job, one must
rely on detailed knowledge of the application and on the technical
judgment of…

Metal Coated Microspheres – Conductive Silver Coating

Electrically conductive microspheres are produced by applying a metallic silver coating to the surface of the microspheres, thus giving the advantages of a metal particle with the additional properties of the core microsphere. Typically hollow glass microspheres are silver coated as this offers the combination of a low density filler and a conductive particle. Coatings with…

Microspheres for Coatings Applications (Opaque Polyethylene)

Microspheres are well known in the coatings industry for their use as low-surface-area fillers that offer benefits in viscosity and density control, solids content, application and flow characteristics. Cospheric LLC, a Santa Barbara-based microtechnology company, recently launched a line of opaque polyethylene microspheres that act as a superior opacifying agent and provide maximum hiding power with just one monolayer…
