PROCESS FOR RIGID FOAM OBTENTION FROM A FIBROUS MATERIAL AND FOAM PRODUCED THEREFORE

摘要

Process for rigid foam obtention from a fibrous material and foam produced therefore wherein the rigid foam is produced from several fibrous materials such as cellulose (cellulose slurry), ready to use or recycled paper, vegetal or synthetic fibers or any suitable material, the rigid foam of the invention comprises aninert product having high mechanical resistance and being biologically decomposed, without waste of residue is totally able to be recycled and, depending on the final use of the product, the foam can have thermal, acoustic, fireproofing, fire insulating, cushion, waterproofing, shielding, etc., and obtaining a product having high hardness degree which is controlled during the process.
