Polystyrene/PS  is a synthetic aromatic hydrocarbon polymer made from the monomer styrene. It is one of those polymers which are all over the place. Polystyrene is an inexpensive and hard plastic which is available as both a typical solid plastic as well in the form of a rigid foam material. PS plastic is commonly used in a variety of consumer product applications and is also particularly useful for commercial packaging. The outside housing of the computer you’re using now is probably made of polystyrene, as well as the housings of things like hairdryers, TVs and kitchen appliances. Model cars and airplanes are made from polystyrene, as well as many other toys. There’s also foam packaging and insulation, and a lot of the molded parts on the inside of your car, like the radio knobs.

Polystyrene latex microspheres are micron sized polystyrene particles with spherical morphology. The special part of our polystyrene latex microspheres is our PS beads are with narrow particle size distribution.

EPRUI Biotech provides high quality monodisperse polystyrene beads: crosslinked and non crosslinked polystyrene microspheres for labs or large scale industrial use. The non crosslinked polystyrene microbeads are soluble in solvents such as acetone, chloroform THF, tolune etc. Different with non crosslinked polystyrene spheres, crosslinked polystyrene particles or PS/DVB exhibit much higher physical and chemical stability and are not soluble in organic solvents. PS/DVB microbeads have excellent mechanical strength and disperse well in solvents.

Applications

Different from common type of polystyrene resin, our polystyrene latex microspheres are widely used in the high end field of self arrangement of microspheres, filter membrane screening, fluid dynamics research, photonic crystal film formation, instrument calibration, particle size standard, chromatographic as well as medical and biochemical industries.

Features

  • Highly uniform particle size
  • Perfect spherical morphology
  • Optimized pore structure
  • Good chemical and PH stability
  • High mechanical strength
