PS Microgranulates

Producer: INEOS
Polymer type GP PS, HI PS

Polystyrene microgranulates are spherical beads with a diameter of 0.2 to 1.0 mm.

The products are additive free with a purity of 99.9%. Due to high surface to volume ratio and the excellent mixing properties, these products provide a number of advantages in the manufacturing process of compounds and master batches. Microgranulates are available as crystal and high impact grades from Styrolution.

PS microgranulates main characteristics:

  • Polystyrene with high surface to volume ratio
  • Spherical particles, Average size: 200 to 1000 μm
  • Produced in a suspension polymerisation process
  • Crystal and HIPS grades available
  • Food contact grades available
  • Due to high surface area
    • No additional grinding/repackaging etc.
    • Better mixing and dispersion
    • Higher additive loading
    • Better homogeneity
    • Faster dissolving
  • Spherical particles; less agglomeration, easier processing
  • High purity
  • No thermal history
