FIELD: chemistry.
SUBSTANCE: invention relates to polyurethane foam material, method of obtaining polyurethane foam material, premix for obtaining polyurethane material and product, containing foam material. Polyurethane foam material represents product of reaction of mixture: (a) isocyanate-based reagent; (b) optional compound, which reacts with isocyanate, and protein-containing composition, capable of reducing density of polyurethane foam material by at least 5% relative to polyurethane material, obtained from the same mixture but without protein-containing composition.
EFFECT: obtaining renewable, less expensive and more environmentally friendly agents which can modulate properties of foam materials.
