Clear Polyethylene Microspheres 0.96g/cc - 1um to 1700um (1.7mm)
Description
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)
