Cospheric Microspheres 









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.

New Products:
UV Fluorescent microspheres 1um-5um (red, orange, yellow, green, blue)
PMMA microspheres  in sizes of 10-27um, 27-45um and 45-53um
Hollow glass microspheres in sizes 27um to 150um
 
R&D samples ship in 1-3 business days.

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?
