Extir® A 5000 AE

Extir A 5000 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 A 5000 AE is suitable for production of low-medium density blocks for the thermal insulation sector.

Extir A 5000 AE is used mainly in the construction sector where, for legislative or safety reasons, the use of a flame retardant material is required.

Typical applications are:

• blocks, especially for external thermal insulation

• low density elastified 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
