Material Safety Data Sheet - Polyethylene
Spheres, Beads, Microspheres, and Nanospheres
Green 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. 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.
Particles in Size Range: > 90%
