Title: The Innovations of Carl William Liskey
Introduction
Carl William Liskey is an accomplished inventor based in Chicago, IL (US). He has made significant contributions to the field of materials science, particularly in the development of advanced foams. His innovative work has led to the creation of a patented technology that enhances the performance of rigid foams.
Latest Patents
Liskey holds a patent for "Imide-containing polyester polyols and intumescent rigid foams." This patent describes rigid polyurethane or polyisocyanurate foams, along with the polyester polyols used to produce them. The formulation methods for these foams are also disclosed. The foams consist of a reaction product of a polyisocyanate, a polyester polyol, water, a surfactant, a catalyst, and optional ingredients. The polyester polyols include a phthalimide-containing polyacid, a phthalimide-containing polyol, or a combination of both. Rigid foams produced from these polyester polyols exhibit higher thermal stability and greater intumescence compared to foams made from other polyester polyols. This innovation allows formulators to improve the flammability performance of rigid foams while using reduced levels of flame retardants and facilitates the production of thinner insulation panels.
