EPRUI Nanoparticles&Microspheres Co. Ltd. provides a series of highly crosslinked monodisperse polystyrene microparticles. In contrast to non crosslinked monodisperse PS microspheres, polystyrene-divinylbenzene microspheres exhibit much better physical and chemical stability and are insoluble in organic solvents. Monodisperse polystyrene-co-divinylbenzene microspheres have excellent mechanical strength and good dispersibility. The specifications of monodisperse PS-DVB microparticles can be supplied as below:
