Polymer Spheres and Microspheres

CATEGORIES
High quality solid polyethylene microspheres available not only in a wide variety of colors, but also with opaque, paramagnetic, fluorescent, and phosphorescent properties. Some polyethylene microspheres have a strong triboelectric (electrostatic) charge.
Poly(methyl methacrylate) or PMMA microspheres are often used as spacers, medical fillers, and cores for metal coated spheres in a wide variety of applications including porous ceramics, self assembled microfluidic devices, biomedical research and life sciences.
Polypropylene Spheres are highly spherical plastic particles. Large, highly-spherical particles of density less than 1g/cc are a useful tool as reference particles in simulation experiments and process troubleshooting.
Polystyrene Spheres are highly spherical plastic particles in sizes between 2mm and 4.5mm. Large, highly-spherical particles of density greater than 1g/cc are a useful tool as reference particles in simulation experiments and process troubleshooting.
Large Cellulose Acetate Spheres are highly spherical plastic particles that are offered in a selection of bright colors and sizes between 1mm and 12mm. Cellulose Acetate Spheres have high impact and mechanical strength as well as high dielectric constant and good resistance to a variety of chemicals.
