Polyurethane modified polyisocyanurate and other polyurethane materials are similar, but the materials will perform differently under some service conditions. Polyurethane modified polyisocyanurate and other polyurethane materials are similar, but the materials will perform differently under some service conditions.

The thermal insulation is produced by the polymerization of polymeric polyisocyanates in the presence of polyhydroxyl compounds, catalysts, cell stabilizers, and blowing agents. Additional test data such as tensile strength, com- pressive resistance, and dimensional stability may be helpful in determining the end use suitability. Polyisocyanurate thermal insulation is commonly available in lengths up to in. It should not be exposed to?
