Enhancing Polyurethane Foam Formation with Tris(Dimethylaminopropyl)Hexahydrotriazine for Improved Insulation Properties Abstract Polyurethane (PU) foams are widely used in various industries due to their excellent thermal insulation properties, durability, and versatility. However, traditional PU foams often suffer from limitations such as poor flame retardancy, inadequate mechanical strength, and suboptimal thermal performance. This paper explores the use...
