A wide range of polyurethane foam products is available in various densities and open-cell content, each exhibiting different performance characteristics such as application temperature, moisture resistance and R-value, and compressive strength.
Use of sprayed polyurethane foam (SPF) insulation has steadily become more widespread. Used in residential and commercial structures of various types, SPF is a high-performance option for the building envelope.
Polyurethanes have the broadest range of any product group, but they tend to combine toughness and flexibility with adhesive properties. This article examines the chemistry behind these coatings, seeking to give specifiers the information needed to select the right material for a project.
The 2014 Polyurethanes Technical Conference, hosted by the Center for the Polyurethanes Industry (CPI) of the American Chemistry Council (ACC), takes place September 22 to 24 at the Gaylord Texan Resort and Convention Center in Dallas.
