Abstract
The effect of the composition of a polyisocyanate–polyester–foaming agent mixture on the density, the thermal conductivity, the mechanical properties, and the thermostimulated shrinkage of polyurethane foams is studied. Nonshrinking foams with a shape stability and a thermal conductivity of 0.0234–0.0310 W m–1 K–1 are prepared. A change in the polyisocyanate/polyester ratio makes it possible to control the thermostimulated foam shrinkage in the range from 0 to 78%.
