WebThe heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K.It is a measure of a substance’s ability to transfer heat through a material by conduction.Note that Fourier’s law applies for all matter, regardless of its state (solid, liquid, or gas), therefore, it is also defined for liquids and gases. Polystyrene, abbreviated as PS, is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene, which is derived from benzene and ethylene, both petroleum products.
