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.
Microspheres are supplied in dry powder form and are color stable in
solution. No solvents are used in the manufacturing process.
Polyethylene is inert to most solvents.
