Polyurethane foam for production of sandwich elements, tubes and other products contains sub-micron particles of layer silicate with a specified range of thickness and length

摘要

Foam based on polyisocyanate poly-addition products (I), containing layer silicate particles with a thickness of 1-10 nm and lengths of less than 200 nm. Independent claims are also included for: (1) a method for the production of foam based on (I) in which layer silicates are used; and (2) foam obtained by this method.
