We manufacture uniform plain polystyrene (PS) nano and microspheres in size ranges from 30nm to 15µm. Particles are synthesized by emulsion polymerization or seeded emulsion polymerization which result in a very narrow size distribution. Two types of surface-modified PS latex particles are available: Carboxylated PS latex and Aminated PS latex. These surface modifications cause the particles to be more hydrophilic in nature than our unmodified latex.
