Hydrocarbon blown rigid polyurethane foam for the boardstock industry - a novel approach

摘要

Rigid polyurethane foams are known for their outstanding combination of density, thermal resistivity, structural and fire performance and cost-effectiveness. The effects of selected polyurethane formulation and processing variables on the key polyurethane foam and laminate board performance characteristics were studied. Formulation variables examined include pentane composition, index, and fire retardant. Processing variables examined include temperature, laydown and the physical state of the blend.
