Trama

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.
