Foam plates with improved thermal insulation properties and method for their fabrication

Foam slabs have an anisotropy such that the cells are compressed in the direction of the slab thickness, the foam slabs having a bulk density between 15 and 45 kg/m and the ratio between the long axis and short axis in the compressed cells being between 1.2 and 1.6. The foam slabs have improved ther...

Summary:Foam slabs have an anisotropy such that the cells are compressed in the direction of the slab thickness, the foam slabs having a bulk density between 15 and 45 kg/m and the ratio between the long axis and short axis in the compressed cells being between 1.2 and 1.6. The foam slabs have improved thermal insulation properties.
