DOWNLOAD EBOOK →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

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →A complete overview of a key plastic One of the most versatile polymer materials, polyurethanes have a unique chemical nature that allows for shaping and molding to fit all sorts of consumer and industrial products – seat cushions, carpets, insulation, coatings, and refrigerators to name a few. Despite its popular uses, polyurethane science has only relatively recently achieved appreciation for the richness of its expression as a polymer family. This book provides a thorough presentation of polyurethane science, technology markets and trend analysis based on recent patents. Although it does not provide ultimate detail (such as explicit information typically in patents), the book has a flow and continuity that allows readers to find all the background necessary to understand any other more detailed polyurethane information found elsewhere. Anyone involved in the polymer and plastics industry will find this book a key resource with features that include: An in-depth summary of the current state of polyurethane research and knowledge Discussion of the applications, manufacture, and markets for polyurethanes Analytical methods, reaction mechanisms, morphology, theoretical techniques, and the selection of chain extenders Polyurethane flexible and rigid foams, elastomers, coatings, adhesives, and medical applications In-depth coverage of governmental regulations, non-isocyanate/non-phosgene routes to polyurethane structure, and industrial routes to environmental, health, and safety risk mitigation
