Abstract:Polyisocyanurate (PIR) foam is a thermal insulating material widely used in many industries such as construction, refrigeration, piping/tubing among others. In this research the production, characterization and modeling of the thermal conductivity of PIR foams synthesized with a hydrofluorolefin (HFO 1233zd (E)) as physical foaming agent have been studied. The results have shown that increasing the amount of HFO reduces the density, but the cellular structure is not modified. The relative mechanical properties… Show more
