Material Safety Data Sheet - Polyethylene
Spheres, Beads, Microspheres, and Nanospheres
Grey polyethylene microspheres of high sphericity and tightly defined
particle size distribution are used in industrial and scientific
applications for process control, diagnostics, and medical device
technology. These spherical polymer particles are specifically designed with density ~1g/cc for suspension in fresh water, enabling flow visualization and 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.
Polyethylenemicrospheres are hydrophobic and need to be coated with a surfactant prior to suspending in water or aqueous media. We recommend
Tween 20 or 80 Bio-compatible Surfactant.
