Material Safety Data Sheet - Polyethylene Spheres, Beads, Microspheres, and Nanospheres


When applied in a thin layer, these color-changing polyethylene microspheres appear translucent or almost invisible on the surface. However, when illuminated by 365nm UV light they exhibit a strong fluorescent response and appear brilliant yellow-green. This feature is very useful in doing experimentation and blind tests especially in medical technology industry, diagnostics, troubleshooting, process flow, medical research and other industries.

The spheres are supplied in dry powder form. Polyethylene microspheres are hydrophobic and need to be coated with a surfactant prior to suspending in water. We recommend Tween 80 Bio-compatible Surfactant.
