White polymer microspheres are made with Titanium Dioxide (TiO2) and are safe to use for personal care applications. White PE spheres are extremely opaque, offering maximum hiding power even in a small layer of spheres. Opaque white particles act as a superior opacifying agent that offers advantages in paints and coatings, cosmetics and personal care applications.
Other colors, sizes and grades of polyethylene spherical particles are available: Polyethylene Microspheres (Colors, Fluorescent, Phosphorescent, Barium Sulfate)
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:
WPMS - generic white polyethylene microsphere product, does not have a specific density usually between 1.0 and 1.3g/cc
WPMS-1.00 - density of 1.00g/cc, tolerances +/- 0.03g/cc
WPMS-1.05 - density of 1.05g/cc, tolerances +/- 0.03g/cc
WPMS-1.10 - density of 1.10g/cc, tolerances +/- 0.03g/cc
WPMS-1.15 - density of 1.15g/cc, tolerances +/- 0.05g/cc
WPMS-1.25 - density of 1.25g/cc, tolerances +/- 0.05g/cc
WPMS-1.35 - density of 1.35g/cc, tolerances +/- 0.05g/cc
White polyethylene microspheres are supplied in dry powder form. No solvents are used in the manufacturing process.
Particles in Size Range: > 90%
Spherical Particles: >90%
