Polyethylene microspheres are hydrophobic and suspend easily in oil-based solutions. They can also be suspended in aqueous solution if coated with a surfactant prior to suspending in water. We recommend using Tween 80 or Tween 20 Surfactants. Following densities are available:WPMS-1.00 - density of 1.00g/cc, tolerances +/- 0.03g/cc WPMS-1.05 - density of 1.05g/cc, tolerances +/- 0.03g/cc WPMS-1.10 - density of 1.10g/cc, tolerances +/- 0.03g/cc WPMS-1.15 - density of 1.15g/cc, tolerances +/-...

PMMA polymer is an amorphous, transparent and colorless thermoplastic that is hard and stiff. It has good abrasion and UV resistance and excellent optical clarity. PMMA spheres are soluble in organic solvents such as acetone, benzene, or halogenated hydrocarbons. Though flammable, PMMA material has low smoke emission.PMMA microspheres have good biocompatibility which allows the particles to be used in many medical and biochemical applications. PMMA spheres also make an effective bondline...

Properties of Polystyrene Microspheres Polystyrene microspheres are in their most pure form, with no surface functionalization, coatings or colorants added. Crosslinked polystyrene is inert, chemically stable, and safe for handling. The primary safety precaution is minimizing inhalation of dust for particles less than 10 micron in diameter. Shelf life is 3 years for unopened products and 1 year after the product has been opened. These polystyrene microparticles are offered as a dry powder,...

Janus particles are microspheres with dual-functionality. We specialize in creating hemispherical coatings on microspheres of any material with diameters greater than 45micron. Custom colors, cores, sizes can be made as a special order. The spheres were originally developed for very high tolerance electronic digital displays where functionalized janus microspheres are used to create an image that appears to the viewer.

Silica spheres are manufactured using proprietary technologies which allow the essential properties of amorphous silica to be maintained while simultaneously achieving controlled spherical shape and uniform particle size. Untreated silica spheres are typically hydrophilic and negatively charged. However, these parameters are not fixed, and might vary depending on the properties system the spheres are incorporated into.

Bondline spacer grade solid soda lime glass microspheres are available with tight particle size ranges to achieve bondline thickness (gap) from 10micron (0.01mm) to 500micron (0.5mm). Bondline spacers are supplied as a dry powder. We recommend using ~5% of spheres by volume (~10% by weight) in epoxy bondlines. Other size ranges of soda lime glass spherical particles are also available in broad sizes from 10um to 7.1mm. If you don't see the size you need below please contact us and we will make...
