Polyurethane and Related Foams chronicles the scientific and technological evolution of preparation and processing methods for polyisocyanate-based foams.

Features:

• Classifies the chemistry and processing of flexible foams, rigid foams, fibers, films, resins, elastomers, coatings, sealants, and other polyurethane products
• Discusses the synthesis of foams using multiple-step reactions, catalysts, blowing agents, polyols, and other starting materials
• Examines reactions and processing methods used to improve strength, flexibility, thermal stability, fire-resistance, and other properties in foam products
• Emphasizes the technological advances and continuing research driven by environmental, safety, and quality demands
• Highlights the development of next-generation blowing agents including HFCs, C5-hydrocarbons, water, and liquid CO2
