White barium sulfate polyethylene microspheres are supplied in dry
powder form and are stable in solution.
Polyethylene microspheres are hydrophobic and suspend easily in
oil-based solutions. They can also be suspended in aqueous solution if
coated with a surfactant prior to suspending in water. We recommend
using Tween 80 or Tween 20 Surfactants.
