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

Product Line: CPMS

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)

Questions:
Hello, Exactly what does the microsphere density represent? If I wanted to calculate a volume for the microspheres from their weight, what would you recommend is the best way to do this?
Answers:
Thank you for your question. The Density listed on our products is the true particle density. When calculating the number of spheres per gram, we recommend utilizing the mean diameter of the specified size range, and this true particle density. We have pre-calculated the estimated mass per gram for a number of our typical size ranges and densities at the page below: https://www.cospheric.com/calculations_of_spheres_per_gram.htm
