Material Safety Data Sheet - Polyethylene
Spheres, Beads, Microspheres, and Nanospheres
Long-afterglow yellow-green phosphorescent spherical particles are supplied in dry powder form. Controlled particle size ranges enable investigation of maximum particle size passing through the openings, filters and membranes. Phosphorescent particles are used for process study and blind tests especially in medical technology industry, diagnostics, troubleshooting, process flow, medical research and other industries. Particles exhibit a strong long-afterglow phosphorescent response and are stable in solution.
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: 1.06-1.16g/cc varies by size and lot, 1.11-1.16 is typical.
