Thermophysical Properties of Polystyrene and Poly (Vinyl Chloride).

摘要

This technical report presents the most comprehensively compiled experimental data and the critically evaluated and recommended reference values for the thermal conductivity,specific heat,density,and thermal diffusivity of polystyrene and poly(vinyl chloride). The compiled data include all the experimental data available from the literature. The recommended values generated from critical evaluation,analysis,and synthesis of the available data and information are for solid (unexpanded) polystyrene with a density of 1.050 g/cc,for foamed polystyrene expanded with air with densities of 0.060and 0.010 g/cc,for solid poly(vinyl chloride) with a density of 1.400 g/cc,and for foamed poly(vinyl chloride) expanded with air with densities of 0.060and 0.020 g/cc. The temperature range covered by the compiled data on some of the properties is from cryogenic temperatures to above the melting point of the material. The recommended values for polystyrene cover the temperature range from 100to 600 K and those for poly(vinyl chloride) cover the range from 100to 400 K.
