FIELD: construction materials.
SUBSTANCE: present invention relates to foamed polyurethane used in construction, particularly for making heat-insulating plates for interior finishing. Said foamed polyurethane contains 100.0 wt.pts. oligoester amide based on terephthalic acid diamide, 12.0 wt.pts. glycerine, 12.0 wt.pts. triethanolamine, 30.0 wt.pts. sodium polyacrylate, 5.0 wt.pts. water and 60–80 wt.pts. methylene diphenyl diisocyanate.
EFFECT: obtained foamed polyurethanes have improved heat-insulating properties when used as hydroxyl-containing component oligoester, obtained on the basis of products of chemical processing of polyethylene terephthalate wastes.
