Application

Polystyrene can be added to nanocatalyst suspension to prepare a polystyrene-photocatalyst thick film. This film can be used as a photoanode in an airlift photocatalytic fuel cell (APFC).

Polystyrene can be used as a precursor to prepare graphene film and 3D graphene sponges by pyrolysis under argon atmosphere. The filmogenic property of polystyrene can be exploited to prepare 3D graphene sponges with uniform pore sizes.

It can also be used to prepare dyed polystyrene (PS) film for routine dosimetry in radiation processing. Dyed PS film has high post-irradiation stability.

Features and Benefits

  • With a high molecular weight of ~280,000, our polystyrene delivers high rigidity and durability, ideal for packaging, and insulation.
  • Glass transition temperature of ~100 °C ensures stability in moderate heat, making it a good choice for electronics, and labware.
  • A refractive index of 1.5916 and a consistent density of 1.047 g/mL, offers superior optical clarity and precision—ideal for transparent containers, lenses, and molded parts.
  • Offered in convenient beads or pellets, to ease the process across a wide range of manufacturing setups.

General description

Polystyrene is a high molecular weight aromatic synthetic polymer madefrom the polymerization of styrene. It is a hydrophobic durable thermoplasticwidely used in food containers, packaging foam, and construction materials dueto its good mechanical properties and low cost.
