Effect of talc filler on physical properties of polyurethane rigid foams

This article reports on the properties of polyurethane rigid foams, which are used as insulating materials. Most polyurethane rigid foams, derived from cellular polymers, are unstable and tend to crack when acted upon by external forces. These foams are classified as a subgroup of cellular polymers, and thus their low stabilization levels can be partly explained by the fact that they contain cells. In these experiments, we attempted to add talc, to polyurethane rigid foams, as a filler, in an attempt to investigate its effect on the physical properties of the constructed foams in both horizontal and vertical directions. Physical and comparative tests were performed on various compositions of polyurethane foam to chart their insulating capabilities, and our comparative analysis indicated that advances had been achieved with respect to some of its properties.
