Extir® B 5000 AE

Extir B 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 B 5000 AE is used for production of medium density blocks for the thermal insulation sector. This grade is characterised by fast moulding cycles, good fusion and low energy needs. The cut board exhibits high mechanical strength and good surface finishing.

Extir B 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

• medium / high 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
