    Notes: Shortages of both energy and materials make it imperative that low cost substances, processed with low energy requirements, be developed as soon as possible. One promising type of materials are the structural thermoplastic foams since they further enhance the favorable strength to weight ratio of plastics while reducing overall material needs. In addition, foam processing also capitalizes on the generally lower energy consumption and manpower-hour requirements for plastics. Finally, the possibility of forming larger and more complex shapes opens up new application areas. The largest deterrent to the use of structural foams is the lack of appropriate basic engineering and scientific knowledge. This paper not only summarizes and extends such understanding, but also shows how appropriate design procedures can be developed.

    Notes: General correlations were developed to estimte polymer thermal conductivities for four cases - amorphous polymers above the glass temperature; amorphous polymers below the glass temperature; semicrystalline polymers above the melting temperature, and semicrystalline polymers below the melting temperature. The correlations based on readily available parameters (mer weights, densities at 25°C, specific heats) yielded calculated thermal conductivities that deviated by only 1%-2% from experimental values.
