Description

Looking beyond the traditional applications of polyurethanes (PUR), Polyurethanes as Specialty Chemicals presents a different approach to polyurethane chemistry by examining a range of new products and new research for both environmental and medical applications. This book is also the first in its field to provide useful design tools for product designers to customize the foam surface.

The author examines extraction methods and biodegradability of polyurethanes for removing pollutants from air and groundwater and for sanitation/wastewater treatment. Thomson also explores the behavior of polyurethanes in a biological environment, covering a broad spectrum of applications that includes artificial organs, chelating agents for pharmaceuticals, and delivery systems for skin care products and cosmetics. The in-depth treatment of biochemical processes and cellular interaction includes tissue response, cell adhesion, 3D cell scaffolding for cell propagation, the immobilization of enzymes, and the production of proteins. Other topics of interest include agricultural applications and the use of PUR as an analytical/diagnostic system for testing toxicity without the use of animals.

Destined to become indispensable in its field, Polyurethanes as Specialty Chemicals explores conventional PUR and its composites - emphasizing formulations, reticulated foams and hydrophilics - as versatile structures that can be used for specific design objectives in environmental and medical applications.

Reviews

"The reference section combines historic and current literature, with an excellent glossary at the end. The figures and photos are of high quality, and experimental data are added to reinforce the argument as to the versatility of polyurethanes. The book should serve as a very good reference to those considering the design of new products in the general areas of environmental-, pharmaceutical-, medical-, and bio-technology and is highly recommended."

- Polymer News, May 2005

"The Author is an expert in the field of PUR chemistry. This text provides a comprehensive coverage on a wide range of topics from physical properties of the material to its application in the chemical, medical, and biochemical industries… The author has a very lucid style of writing."
