Abstract
Following a number of government & industry sponsored workshops, the conclusion was reached to fully evaluate hydrochlorofluro- carbons for their suitability as blowing agents in PIR laminated boardstock. Laminate boardstock was chosen because of its commercial significance, high technical dependence on alternate blowing agents and diverse requirements. For the first time in our industry, it was possible to bring together leaders from raw material manufacturing companies, insulation foam producers, product end users, and two interested government departments. A specific PIR formulation and organic/inorganic facer were selected as logical industry choices generally representing current roof insulation technology. With this as a base, it became the goal of the project to compare potential HCFC alternative blwoing agents versus the current industry standard CFCj-11. The participating labs measured the full range of physical and mechanical properties of the pilot plant and plant-produced boards establishing conformance with industry specifications. Combustibility properties as determined by recognized test procedures for roof insulation were performed by independent testing labs to compare blowing agent effects on combustibility behavior.
