Building Heat-insulating Materials Based on the Products of the Transesterification of Polyethylene Terephthalate and Dibutyltin Dilaurate☆

Abstract In this paper, we offered a technological basis for production of heat-insulating polyurethane materials based on the aromatic polyester – the product of transesterification of polyethylene terephthalate and corrective additive - dibutyltin dilaurate. Also, we presented the formulation and properties of the developed polyurethanes.
