    SCOPE OF REPORT

    BCC analyzes the global market for microspheres from both the manufacturing and demand points of view. Since there are several types of microspheres that vary drastically in quality, chemical properties, functionality and price, each type of microsphere is discussed in detail, including materials, manufacturing processes, advantages, prices and primary applications. Similarly, due to these variations microsphere use in six major industries are discussed and analyzed in detail.

    Detailed analysis and market forecasts are provided per industry, type of microsphere and geographic region through 2018. The report describes major players in the industry and examines recent advances in technology, newly evolving markets and companies as well other factors influencing supply and demand.

    This report analyzes microspheres—homogeneous microparticles of 1 micron to 1,000 microns in diameter. Microspheres can be solid or hollow and made from a variety of raw materials.

  • Negatively-charged Yellow Microparticles – Back in Stock

    Highly Negative Charged Microspheres - Polyethylene, Selection of Sizes 5 to 500um

    Highly Negative Charged Microspheres - Polyethylene, Selection of Sizes 5 to 500um, 1.0g/cc

    Cospheric’s neutrally-buoyant highly charged yellow microspheres have a strong negative charge and are used by scientists in medical technology, biotechnology, applied physics and research. Precise particles with known density of 1.0g/cc that behave in a known way are useful as a model particles in simulation experiments.  Particles in a range of diameters from 5micron to 500micron(0.5mm) are currently back in stock.

    Bright yellow polymer microparticles of high sphericity are spherical polyethylene beads that are specifically designed with density ~1.0g/cc for suspension in fresh water,  serving as seed or tracer particles and enabling flow visualization and Particle Image Velocimetry PIV analysis of fluid flow in a device. It is often advantageous to color code the particles by size to better understand which part of the process the spheres of the specific size were able to pass through, or where the contamination in the process is coming from. Microspheres are supplied in dry powder form and are color stable in solution. No solvents are used in the manufacturing process. Polyethylene is inert to most solvents.

    Cospheric also offers unique capability to manufacture Bichromal janus microspheres and microparticles with partial coatings and potentially dual functionality. Currently half-shell or hemispherical coatings can be applied to any sphere (glass, polymer, ceramic) in sizes 45micron in diameter and higher. Coatings can be customized for any color and coverage of between 20% to 60% of the sphere. Each coating is custom formulated for color, charge, magnetic, electric, and surface properties, and solvent resistance per customers’ needs. Hemispherical coatings of less than 1 micron with tolerances as low as 0.25 micron have been routinely demonstrated.  Color combinations are truly unlimited. White, black, silver, blue, green, red, yellow, brown, purple as well as transparent microspheres have been made. Sphericity of greater than 90% and custom particle size ranges are offered.

    It would be interesting to combine these highly charged yellow microspheres with a partial paramagnetic black coating and investigate the behavior of these spheres in electromagnetic field.

  • Silane and Fluorochemical Coated Glass Spheres

    Solid glass imparts visual and material benefits that cannot be replicated when spheres are made of other materials such as ceramics or polymerics, aluminum oxides, or silicas and mineral fillers. Solid glass refracts [bends] and reflects light. Most ceramics [with exceptions] do not transmit light or exhibit specular [mirror-like] reflection due to their internal crystalline structures and surface irregularities. Instead of being reflected back, the light is “trapped” in the structure and emitted as diffuse or scattered reflectance, which is not as strong or direct as light transmitted through glass, which produces mirror-like reflectance.  Prizmalite glass spheres distributed by Cospheric offer off the shelf pre-coated spheres for enhancing these effects.

    Silane coated solid glass spheres with increased hydrophobicity are offered to improve the dispersion of spheres throughout paints and coatings.  Silane coated spheres are not recommended for pure water solutions as the spheres will be too hydrophobic to wet.

    Fluorochemical Coating is available for paint and coating applications where it is desired to bring the spheres to the top of the surface of the coating.  This is best used in applications where retro reflectance is desired.

    The following products are offered in both Silane and Fluorochemical Coating.
    P2011SL  3-6um mean diameter solid soda lime glass
    P2015SL  8-12um mean diameter solid soda lime glass

  • Magnetic Microspheres – Paramagnetic

    Magnetic microspheres, more accurately called paramagnetic microspheres have unique properties that are useful for a variety of applications.

    Paramagnetism is a form of magnetism that occurs only in the presence of an externally applied magnetic field. Paramagnetic materials are attracted to magnetic fields and hence have a relative magnetic permeability of ≥1 (a positive magnetic susceptibility). The magnetic moment induced by the applied field is linear in the field strength and rather weak.1

  • Calculating microspheres per gram

    During scientific experiment design and analysis it is common to need to know the number of spheres per gram of dry material.  We have put together the table below to help speed up the process.

    If you have material of a density different from those listed in the table, divide the number of spheres per gram in the density ~1.0 g/cc column by the true particle density of your material to get an estimate of the number of spheres per gram.
