Abstract: A polyurethane gel filled with an expanded calcium carbonate offers an improved material for various applications, wherein the advantageous gel properties are retained, but at the same time negative properties, such as relatively high specific weight and high thermal conductivity, are avoided.

Abstract: The invention relates to the use of a gel mass based on reaction products of polyols and polyisocyanates, wherein the polyol component consists of one or more polyols with hydroxyl numbers below 112 and where appropriate other polyols and additives known from polyol chemistry, the isocyanate number of the reaction mixture lies in the range of 15 to 59.81 and the product of the isocyanate functionality and the functionality of the polyol components is at least 6.15, as a coupling medium for transmitting acoustic waves from a sound source onto the body of the patient.
