摘要

Process for obtaining foams, hydrophilic polyurethane for flower support, characterized in that in its embodiment comprises the steps of dispersing in a polyol 2 to 5 parts by weight of a green dye, selected from those compatible with polyurethane polymers and incorporate, under powerful stirring, 83 parts by weight of said dispersion to 110 parts by weight of a diphenylmethane diisocyanate, preferably containing 27% of nco groups, and followed or simultaneously with the doses of water and usual components in this type of reaction, the which begins in a period less than a minute, beginning the development of gases and foaming of the reactive mass.
