GEL MIXTURE AND ITS PREPARATION

摘要

Improved gel compositions based on products of the reaction of polyols and polyisocyanates are characterised in that the polyol component comprises a mixture of a) one or more polyols having hydroxyl numbers of less than 112 and b) one or more polyols having hydroxyl numbers in the range from 112 to 600, and the isocyanate number of the reaction mixture is in the region of 15 to 70. They can be used as pressure-distributing elements.
