Material Safety Data Sheet - Polyethylene
Spheres, Beads, Microspheres, and Nanospheres
Bright red spherical polymer particles are supplied in dry powder form and are color-stable in solution. Controlled particle size ranges enable investigation of maximum particle size passing through the openings, filters and membranes.
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%
Spherical Particles: > 90%
In-stock orders ship in 1-2 business days. Please contact us for custom size ranges or volume pricing.
