Versalis Extir® Verdi VR A5000 AE Expandable Polystyrene - Flame Retardant
Categories: Polymer; Thermoplastic; Polystyrene (PS); Expanded Polystyrene (EPS)

Material Notes: b>Product Description:
  • Extir Verdi VR A5000 AE is a flame-retardant expandable polystyrene in the form of spherical beads of medium-large particle size, containing pentane as blowing agent.
  • Extir does not contain CFC or HCFC.
  • Extir VR A5000 AE is an improvement of A 5000 AE showing an improved thermal conductivity.
  • Extir A5000 AE is used for production of low-medium density blocks for the thermal insulation sector.

Applications: Extir Verdi VR A5000 AE has an improved thermal conductivity value, especially at low density. Extir VR A5000 AE is used mainly in the construction sector where, for legislative or safety reasons, the use of flame retardant material is required.

Typical applications are

  • blocks, especially for external thermal insulation
  • low density elasticized blocks for impact sound absorption (Trittschall)
  • void formers, trough formers and culvert formers cut from block
  • blocks or slabs for road foundations and civil construction
