FIELD: chemistry.
SUBSTANCE: invention refers to a method for producing elastic urethane foam and to the urethane foam produced by implementing this method. The method for producing the elastic urethane foam involves dispersing an organogel material in a reaction mixture containing a foaming substance, and foaming the mixture. The elastic urethane foam produced by the above method possesses the following characteristics: density of 25 to 120 kg/m3, elasticity more than 35% measured at 20°C in accordance with ASTM D 3574 H requirements, ILD hardness 60 to 500 H at a 40% impression measured in accordance with ISO 2439 B requirements.
EFFECT: invention enables producing the urethane foam having good physical and thermophysiological properties, particularly pressure distribution.
