Pure polyethylene polymer microspheres in dry powder form. No solvents, additives, or colorants are used in the manufacturing process.
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.
Other colors, sizes and grades of polyethylene spherical particles are available:Polyethylene Microspheres (Colors, Fluorescent, Phosphorescent, Barium Sulfate)
