Abstract

The applications of both open- and closed-cell cellular plastics for use as thermal insulations to improve energy efficiency in buildings and industrial processes are discussed. Brief details of the types and forms of cellular plastics available for such uses are included as well as typical data on thermal and other relevant performance properties and characteristics. Materials include extruded and expanded polystyrene, block, laminated and sprayed polyisocyanurate (including polyurethane), and phenolic resin based together with a variety of lesser used special application materials such as polyethylene, polyimide, and melamine. The temperature-dependent properties discussed are thermal performance including aging phenomena and its required accelerated aging testing procedures, mechanical, and structural performance. Flame resistance and other fire-related parameters are also included as are health and safety issues including environmental effects of CFC and HCFC-type blowing agents. Finally a brief discussion is included on economic aspects and growth potential of cellular plastics for applications that require thermal insulation for energy efficient operation.
