Black Paramagnetic Polyethylene Microspheres 1.2g/cc - 10um to 1400um (1.4mm)
Description
Cospheric offers black paramagnetic microspheres in dry powder form, which has enabled scientists to leverage the benefits of paramagnetic particles in new applications.
These highly spherical polyethylene microspheres offer the flowability and visibility of larger microspheres, with the ability to be separated from other materials for reuse and cleanup.
Other colors, sizes and grades of polyethylene spherical particles are available:
Polyethylene Microspheres (Colors, Fluorescent, Phosphorescent, Barium Sulfate)
Specifications
Paramagnetic microspheres have the ability to increase their magnetization with an applied magnetic field and decrease their magnetism when the field is removed.
No residual magnetization is observed which provides practical advantages for end uses, including ease of separation and suitability for automation. When the magnetic field is removed, the microspheres demagnetize and redisperse easily.
No solvents are used in the manufacturing process. The micropsheres are highly opaque particles with maximum hiding power.
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.
