Book Description :

Flexible polyurenthane foams of all types are a unique group of plastics materials, characterized by the fact that a multitude of different sets of properties can be obtained by varying the levels of a relatively small number of base components in the formulations. Different foam grades, primarily characterized by density and hardness, can be obtained by changing the ratio between base polyol, polymer polyol, water, blowing agent, isocyanate and other components. It is not uncommon for foam producers in industrialized countries to manufacture more than one hundred different foam grades based on these basic chemicals, plus the ancillary chemicals needed for optimized processing. This has always made flexible polyurethane foams a highly suitable candidate for correlating these variations in the formulations with the resulting properties in a mathematical way, aimed at predicting the properties as accurately as possible, fine-tuning existing grades or designing new foam grades. This book discusses the methodology for obtaining meaningful equations for correlating properties with formulation variables and other influencing factors

Book Description :

The technology for the recovery, reprocessing and reuse of automotive polyurethanes in Europe is highly developed and serves as a successful example for other areas. This new book by a leading authority on this technology details the materials and methods, as well as the problems, involved in this work. Going beyond recovery, the authors examine the processes and applications involved in putting recovered material to economic use in marketable products. The text is supplemented with more than 60 tables providing useful data on polyurethane recycling processes and chemistry. More than 60 photographs, micrographs, diagrams and flowcharts illustrate materials, processes and products. In addition to a detailed presentation of this technology, the book provides a review of European regulation and programs dealing with automotive plastics recycling, as well as the voluntary activities of industry organizations and individual companies. The information in this new book will be useful to personnel involved in the research, development and recycling of plastics and other polymeric materials for automotive applications. The details of reprocessing chemistry will be especially useful to polymer chemists working with polyurethanes. Tables Much of the technical data in this book is presented in 64 tables.
