Summary

The effect of addition of dihydroxymethyl urea and products of its condensation with diethylene glycol and thiodiethylene glycol — as modifiers reducing flammability — on the mechanical and thermal properties of rigid polyurethane-polyisocyanurate foams has been investigated. It has been found that the application of the product of condensation reaction of dihydroxymethyl urea with thiodiethylene glycol results in reducing the foam flammability without an accompanying deterioration of mechanical strength properties, as compared with standard foam without modifier.
