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


Black polyethylene (PE) microspheres are supplied in dry powder form. No solvents are used in the manufacturing process. Black paramagnetic polymer microspheres have a strong response to magnetic fields and can be manipulated with a magnet. Highly opaque particles with maximum hiding power.

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

Several densities available:
BKPMS-1.1 - black polyethylene with density of 1.1g/cc, tolerances +/- 0.05g/cc
BKPMS-1.2 - black polyethylene with density of 1.2g/cc, tolerances +/- 0.05g/cc

Particles in Size Range: > 90%
Spherical Particles: >90%
