Polyurethane and Related Foams: Chemistry and Technology

Buy
Polyurethane foams debuted over 60 years ago. At the present time these types of foams make up the largest segment in the thermosetting foam industry. This book describes polyurethane (PUR) and urethane linkage-modified polyisocyanurate (PIR) foams. A characteristic of these foams lies in the versatility of their physical properties, such as flexibility, viscoelasticity, semi- flexibility, rigidness, and heat and flame-resistance at a wide variety of foam densities. This versatility is derived from molecular design by the choice of raw materials and foaming reactions.

For example, polyurethane foams are prepared by the reaction of polyols with polyisocyanates in the presence of blowing agents. The molecular weight and the functionality of polyols affect the resulting foam properties. Polyisocyanates act as the jointing agent of polyols. Therefore, urethane and related foams are recognized as building block polymers.

Blowing agents are the key materials for polyisocyanate-based foams. Due to the ozone depletion problems in the stratosphere, physical blowing agents have gone through a revolutionary change. ChJorofluorocarbons, (CFCs), and hydrochlorofluorocarbons (HCFCs) have been phased out. The next generation of blowing agents includes hydrofluorocarbons (HFC), Cg-hydrocarbons, water, and liquid carbon dioxide. This book highlights this next generation of blowing agents.

This book is intended to be informative to people in research and development, production, processing, testing, marketing, sales, and foam applicators, as well as professors, students, and others.
