POLYSTYRENE PARTICLES
 The polystyrene particles are prepared by using emulsion polymerization process. Particles supplied by Spherotech have been precleaned using either mixed bed ion exchange or by centrifugation. Further cleaning by user is usually not required. The size of particles is determined by either NICOMP Laser Particle Sizer or visually by Scanning Electron Microscope.
  

CROSS-LINKED POLYSTYRENE PARTICLES
Spherotech offers a wide range of cross-linked polystyrene particles. Both non-uniform and uniform shape crosslinked polystyrene particles are manufactured at Spherotech. The low cost non-uniform particles are useful when particle shape does not matter. If a perfect spherical monosized polymer particle is needed, use the 0.5% DVB cross-linked polystyrene particles. Spherotech also provides uniform cross-linked polystyrene particles that are stable in the presence of organic solvents. Futhermore, larger size uniform cross-linked polystyrene particles are also available.
