Abstract

Procedure for the obtaining of a new material from the flexible or semiflexible polyurethane foam, which is essentially characterized by comprising the following operational phases, taken in combination: A - subjection of the polyurethane foam mass to be treated at the necessary pressure to alter in the ideal form the conformation of the original cells. B - application of heat to the mass subjected to pressure in sufficient degree to achieve the fusion of the cell walls to the point that allows the desired moldability. C - maintenance of the dough under the effects of pressure and heat supplied, during the time necessary to obtain the desired conversion of the cells or cells in the fusion state. D - simultaneous release of the mass to the effects of heat and pressure. (Machine-translation by Google Translate, not legally binding)
