Dyed Particles

Monodisperse Blue-colored polystyrene particles have been specifically developed for applications such as filter testing, flow tracing, scientific research, medical diagnostics, and other applications. The coloring of the polymer particles with selected dyes (mainly blue and red) are made using co-polymerization or swelling-deswelling processes. The particles combine high monodispersity (CV < 5 %), spherical shape, low density (1,05 g/cm³), and intensive blue color. Our monodisperse Blue-colored polystyrene particles comprise a large assortment of beads between 1 µm and 100 µm. Monodisperse polystyrene particles wit other colors (for instance yellow, orange, green, black and others) are available on request. All products are delivered as       5 wt.-% aqueous dispersions or as dry powders (above 5 µm).
