摘要：
The invention concerns new compositions on the base of polyurethanes, in particular, polyurethane systems intended for manufacturing elastic products, preferably, for medical purposes, such as, orthopedic antibedsore mattresses, seats-pillows, anatomic pillows, insoles-instep supports, orthopedic corsets, kneecaps, bandage products, footwear for various kinds of defects of foots and the like. Also improved polyurethane wound dressings can be produced. The new modified polyurethanes have improved sanitary and hygienic properties which render them specifically suitable for the claimed uses. The polyurethane system of the invention, with improved sanitary and hygienic properties, contains a polyol compound (component А), a isocyanate compound (component В) and a mineral agent (С) dispersed into the polyol compound (component А). The mineral agent (C) consists of a mix of nanostructured powders of bentonite intercalated by ions of silver(Ag+) and ions of cerium (Ce3+ ), in a ratio between them of 1 : (5-10) parts by weight. The articles produced with the new polyurethane system have clearly improved characteristics in so far as suppression of growths of microorganisms and preventing evolution of volatile toxic organic compounds are concerned.Cette invention concerne de nouvelles compositions à base de polyuréthanes, en particulier des systèmes de polyuréthanes destinés à la fabrication darticles élastiques, de préférence à vocation médicale, tels que matelas orthopédiques anti-escarres, coussins de siège, oreillers anatomiques, supports de semelles intérieures, corsets orthopédiques, protège-genou, bandages, chaussures pour divers défauts du pied et analogues. Ces nouveaux polyuréthanes modifiés possèdent des propriétés sanitaires et hygiéniques accrues qui les destinent spécifiquement aux applications susmentionnées. Le système de polyuréthanes de linvention aux propriétés précitées contient un composé polyol (composant A), un composé isocyanate (composant B) et un age
