Description

Handbook of Polyurethanes, Polyureas, and Polyisocyanurates by George Wypych

Handbook of Polyurethanes, Polyureas, and Polyisocyanurates focuses on the raw materials required for polyurethane synthesis. It explores various isocyanates and polyols, detailing their chemical properties and roles in creating diverse polymer structures. Amines, solvents, catalysts, and other additives that enhance the synthesis process are also discussed, as are typical methods of synthesis, mechanisms of catalysis, factors affecting reaction rates, and potential side reactions that can occur during polymerization. Structures of linear and crosslinked polyurethanes are also covered, including how these configurations influence the physical and chemical properties of the final products. Typical methods for analyzing polyurethanes, allowing for their assessment, characteristics, and qualities are provided, as are the physical-mechanical properties of polyurethanes, including elasticity, tensile strength, and thermal stability. The creation of polyurethane blends and interpenetrating networks is discussed, and the book also features an extensive section on additives used with polyurethanes, such as plasticizers, pigments, flame retardants, and more. Processing methods such as metering, mixing, and storage are outlined, applications of polyurethanes in automotive parts, bedding, medical devices, and packaging are covered, and the book concludes with coverage of waste disposal, processing, and recycling strategies for these products.
