摘要

Visco-elastic polyurethane-foam material (I) preferably for the production of integral foamer of medical padding and editions, comprises polyether polyols; diphenyl methane diisocyanate and/or modified diphenylmethane diisocyanate and/or their mixtures with other polyisocyanate; a propellant in the form of a volatile hydrocarbon; and optionally catalysts and/or usual additives. Visco-elastic polyurethane-foam material (I) preferably for the production of integral foamer of medical padding and editions, comprises polyether polyols; diphenyl methane diisocyanate and/or modified diphenylmethane diisocyanate and/or their mixtures with other polyisocyanate; a propellant in the form of a volatile hydrocarbon; and optionally catalysts and/or usual additives, where the mixing proportion (wt.%) of polyetherpolyol and propellant to isocyanate amounts to 100:25-100:30 and comprises polyetherpolyol (100 wt.%) and propellant (8-3 wt.%) from polyetherpolyol (92-97 wt.%) and (I) exhibits a hardness of 3-7 according to the densimeter (ball 5 mm in diameter). An independent claim is also included for products concerns with mattresses, medical editions, products for padding of free articles or furniture, strongly suspending the fluctuating pressure loads or act as safety measures.
