Material Safety Data Sheet - Polyethylene
Spheres, Beads, Microspheres, and Nanospheres
Orange polyethylene microspheres of high sphericity and narrowly graded 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.
Polyethylene microspheres are hydrophobic and need to be coated with a surfactant
prior to suspending in water or aqueous media. We recommend Tween 80 Bio-compatible Surfactant.
Density: (1.00) = 0.99-1.01g/cc; (1.015) = 1.01g/cc-1.025g/cc
Particles in Size Range: > 90%
Spherical Particles: > 90%
