Book Description
Recycling of Polyurethane Foams introduces the main degradation/depolymerization processes and pathways of polyurethane foam materials, focusing on industrial case studies and academic reviews from recent research and development projects. The book can aid practitioners in understanding the basis of polymer degradation and its relationship with industrial processes, which can be of substantial value to industrial complexes the world over. The main pathways of polymer recycling via different routes and industrial schemes are detailed, covering all current techniques, including regrinding, rebinding, adhesive pressing and compression moulding of recovered PU materials that are then compared with depolymerization approaches. The book examines life cycle assessment and cost analysis associated with polyurethane foams waste management, showing the potential of various techniques. This book will help academics and researchers identify and improve on current depolymerization processes, and it will help industry sustainability professionals choose the appropriate approach for their own waste management systems, thus minimizing the costs and environmental impact of their PU-based end products. - Offers a comprehensive review of all polyurethane foam recycling processes, including both chemical and mechanical approaches - Assesses the potential of each recycling process - Helps industry-based practitioners decide which approach to take to minimize the cost and environmental impact of their end product - Enables academics and researchers to identify and improve upon current processes of degradation and depolymerization

Book Description
Spray Polyurethane Foams in External Envelopes of Buildings presents, for the first time, a book focused on both the theoretical and practical design and applications of spray polyurethane foam (SPF) use. To review the moisture performance of SPF, this book focuses on the design of an assembly where moisture is kept from accumulating and causing deterioration (flow through approach). In this approach, Spray Polyurethane Foam presents two unique parts of theory and practice of various SPF products. FROM THE PREFACE Part 1 of this monograph analyzes SPF performance as the material (product). Being field fabricated, installation of SPF products must include a quality assurance program . . . Laboratory evaluation of foams and their coverings, quality management issues, and quantification of the technical support provided to the SPF contractor are also reviewed. Part 2 presents a systems approach to construction. Starting with principles of environmental control of buildings, different aspects of design and performance of roofing and wall systems are reviewed. Details and design recommendations . . . as well as case studies . . . are included.

Book Description
A practical handbook rather than merely a chemistry reference, Szycher's Handbook of Polyurethanes, Second Edition offers an easy-to-follow compilation of crucial new information on polyurethane technology, which is irreplaceable in a wide range of applications. This new edition of a bestseller is an invaluable reference for technologists, marketers, suppliers, and academicians who require cutting-edge, commercially valuable data on the most advanced uses for polyurethane, one of the most important and complex specialty polymers. internationally recognized expert Dr. Michael Szycher updates his bestselling industry "bible" With seven entirely new chapters and five that are revised and updated, this book summarizes vital contents from U.S. patent literature—one of the most comprehensive sources of up-to-date technical information. These patents illustrate the most useful technology discovered by corporations, universities, and independent inventors. Because of the wealth of information they contain, this handbook features many full-text patents, which are carefully selected to best illustrate the complex principles involved in polyurethane chemistry and technology. Features of this landmark reference include: Hundreds of practical formulations Discussion of the polyurethane history, key terms, and commercial importance An in-depth survey of patent literature Useful stoichiometric calculations The latest "green" chemistry applications A complete assessment of medical-grade polyurethane technology Not biased toward any one supplier’s expertise, this special reference uses a simplified language and layout and provides extensive study questions after each chapter. It presents rich technical and historical descriptions of all major polyurethanes and updated sections on medical and biological applications. These features help readers better understand developmental, chemical, application, and commercial aspects of the subject.

Book Description
Toxic fire effluents are responsible for the majority of fire deaths, and an increasing large majority of fire injuries, driven by the widespread and increasing use of synthetic polymers. Fire safety has focused on preventing ignition and reducing flame spread through reducing the rate of heat release, while neglecting the important issue of fire toxicity. This is the first reference work on fire toxicity and the only scientific publication on the subject in the last 15 years.Assessment of toxic effects of fires is increasingly being recognised as a key factor in the assessment of fire hazards. This book raises important issues including the types of toxic effluents that different fires produce, their physiological effects, methods for generation and assessment of fire toxicity, current and proposed regulations and approaches to modelling the toxic impact of fires.The contributors to Fire toxicity represent an international team of the leading experts in each aspect of this challenging and important field. This book provides an important reference work for professionals in the fire community, including fire fighters, fire investigators, regulators, fire safety engineers, and formulators of fire-safe materials. It will also prove invaluable to researchers in academia and industry. - Investigates the controversial subject of toxic effluents as the cause of the majority of fire deaths and injuries - Describes the different types of toxic effluents and the specific fires that they produce, their physiological effects and methods for generation - Provides an overview of national and international fire safety regulations including current and proposed regulations such as a standardized framework for prediction of fire gas toxicity

Book Description
The purpose of this book is to present in a monographic and systematised form a review of all the literature devoted to polyurethane-based polymeric sorbents in separation chemistry. The primary types of sorbents dealt with are polyurethane foams and open-pore polyurethanes. The structure of the monograph follows this dichotomy. A book of this nature should stimulate thinking and incite its reader to consult the original literature. It will, however, not make such a consultation superfluous. A fair amount of the results described in this monograph constitute the main activity of investigation which took place in the authors laboratories during the past decade.
