Foam specific heat
WebThe conduction of heat in the solid PU structure is a combination of the heat flow in the cell walls and the struts. The thermal conductivity (λPU) of the solid PU polymer from crushed foam samples is reported to be 0,26 W·m-1·K-1 [6] and the fraction of solids in the struts (fs) has been reported to 0,8 [7]. The thermal conductivity [7] can ... WebThis is due to its closed-cell structure consisting of 98% air. This air trapped within the cells is a very poor heat conductor. Hence provides the foam with excellent thermal insulation properties. The thermal conductivity of expanded polystyrene foam of density 20 kg/m 3 is 0.035 – 0.037 W/(m·K) at 10°C.
