Microspheres with Specific Gravity of 1g/cc:

These polymer microspheres with specific gravity of 1g/cc are specifically designed to match the density of water for optimal suspension of particles. Suspension of microspheres in water enables the visualization and characterization of fluid flow and testing the capability of devices to withstand particulate matter in the fluid stream, ensuring that microspheres do not settle and do not float on the surface.  Most of these polymer microspheres are at least moderately opaque and clearly visible in water, clear or translucent liquids.

The following grades of polyethylene microspheres are available with specific density of 1g/cc, designed for optimum suspension in water.

Order 10 gram samples of solid polyethylene microspheres in any of the colors listed below.

Samples ship in 1-3 business days.
