 Microspheres:
We carry a large selection of solid polyethylene microspheres (also known as polymer spheres, balls, beads, microbeads, and microparticles) supplied in dry powder form. We have recently added a selection of PMMA microspheres and hollow glass microspheres.
Custom color microspheres, magnetic microspheres, positively or negatively charged microspheres, functionalized microspheres, coated microspheres can be produced with short lead times. Please contact us with any questions. We respond to all inquiries within 1 business day. R&D samples ship in 1-3 business days.
Core Technologies:
Cospheric specializes in developing and manufacturing custom
microtechnology solutions. We partner with innovative companies
worldwide to add value and competitive advantage to their products
through our unique expertise in microspheres, microcoatings, and microreplicated structures.
We have extensive experience in adhesives, laminations, encapsulation,
solvent-resistance and environmental stability. We can design a
complete system to your specifications.

Technical Articles:
Electrostatic Charge on Microspheres: Measurement Techniques
Electrostatic charge (also known as triboelectric charge) on
microparticles and microspheres have been of interest to scientists in
chemical, pharmaceutical, cosmetic, drug delivery, displays industries. Until recently there were no reliable
techniques to measure or quantify electrostatic charge on
microparticles.
Opaque Polyethylene Microspheres: Applications in Cosmetics and Skin Care
Unique advantage of opaque microspheres in cosmetics is that maximum
hiding power is achieved with one invisible and feather-light layer -
revolutionizing make-up products.
Orientation of Dual-Functionalized Microspheres in Electromagnetic Field
One particularly interesting and unique feature of these miracle
microspheres is their ability to orient themselves in response to
electromagnetic field and show a visual response. This is achieved by
making spheres both bipolar and bichromal, with dipole precisely aligned with two differently colored hemispheres.
Polyethylene Microspheres vs. Glass Microspheres - Properties, Advantages and Applications
With advances in microsphere manufacturing processes,
polymer spheres and glass microspheres are available in comparable
grades, particle sizes and prices. Which microsphere material is right for your
application?
