2. Processing honeycomb materials
A distinction must be made between :
-
primary processing: molding and extrusion with simultaneous foaming for manufacturing :
continuous production of honeycomb semi-finished products such as slabs, blocks, rods and others for further processing,
discontinued parts and finished objects ;
the second transformation to obtain the final part or object from the alveolar semi-finished products.
2.1 Primary transformation processes
Processes can be divided into several categories:
physical expansion of a liquid at low boiling temperature ;...

Markets
The most widely used foams are polyurethanes and expanded polystyrenes, followed at a distance by PVCs, then polyolefins and phenolics. All other products are specialties whose consumption is difficult to assess. The breakdown between cellular PUR and EPS depends on the region in question.
All consumption figures are only average estimates, and other values can be found in the technical-economic literature....
