Abstract
Combustion modified foams are produced by reacting an organic aromatic polyisocyanate with an isocyanate reactive compound in the presence of a blowing agent and Mg(OH).sub.2. The Mg(OH).sub.2 is generally used in a quantity of from 4-100 parts by weight based on the foam taken as 100 parts by weight. Mg(OH).sub.2 having a particle size of from 0.5-50 .mu.m is preferably used. The foams produced by the process are particularly useful in construction applications.
