Grey Polymer MicrospheresOpaque Grey Polyethylene Microspheres
10um to 1000um (1mm)

Cospheric microspheres are the most opaque polyethylene microspheres on the market!

Opacity: Highly opaque
Particle Size Spec:  Microspheres screened to be >90% in particle size range.
Microspheres manufactured to your specific size range needs from 10 micron to 1.2mm.
Shape and Form Spec: Microspheres are >90% spherical in dry powder form.

Density:  0.99g/cc-1.01g/cc
Grey polymer microspheres are specifically designed to match the density of water for optimal suspension of particles. 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.


R&D samples of grey microspheres are in stock and ship in 1-3 business days.
