Description
Book SynopsisEngineering design teams sometimes have need of a material that may not exist because the combination of required properties is difficult to achieve. One solution is to develop a new material having the required set of properties needed in the application. During the author's 40-year career he has successfully worked on many such problems. The uniquely useful and valuable book, Polymeric Thermosetting Compounds: Innovative Aspects of Their Formulation Technology, presents twenty of those design problems and the solutions, which resulted in patents and spin-off applications.
Author Ralph Hermansen, with years of experience of hands-on experience, is an expert in formulating epoxies, polyurethanes, and other polymers into compounds that have unique properties, and here he shares his knowledge and experience of attaining novel solutions to very challenging problems. He covers polymeric compounds such as coatings, adhesives, encapsulants, transparent plastics, and others.
Chapters describe the design problem and define which key properties are sought in the new material. The author shares his thinking about how to approach the formulating problem and describes the experimental procedures used to eventually solve the problem. Patent information is shared as well. Once a new family of polymeric compounds is developed, that technology can be used to attack new unsolved materials problems, or "spin-offs," and real-life examples are provided to help readers see new applications of the technologies described in the earlier chapters.
The book will be of interest to a diverse group of people. Industry professionals already in the business of selling specialty compounds may be able to add new products to their catalogs with little research cost or time by using the information in the book. Formulators, trying to develop a new compound to challenging requirements, may gain insight into how to make a breakthrough. The information in the book will be very valuable to companies needing these novel solutions. And younger people wondering what a career in materials science would be like get a first-hand commentary from someone who has done it.
Trade Review"Ralph Hermansen has capitalized on his well-known reputation in the formulating of high-tech aerospace technology. In this book, he delves into the processes that engineers use to convert raw polymers into compounded systems used to resolve vexing design problems. The text demonstrates a how-to approach to extend successful formulation to new and unexpected product needs. Ralph covers primarily polyurethane and epoxy resins and adds interesting methodology for other types of polymers as well. This compendium will prove useful to experienced compounders, formulators, and designers. Newcomers to the field will also find its advanced primer-like structure helpful."

"The author provides an excellent account of the intricacies of custom formulation based on a career in the industry. The breadth of topics covered, including the very basics to more advanced applications such as aerospace and automotive electronics, makes it a must-have for both students as well as experts. This book fills a substantial need for insight into the formulation process from an industrial expert that discusses not only the scientific approach, but also the inner workings of the important business decisions that are required for successful implementation. The summary of the compounds patented by the author, along with the full explanation of properties and experimental testing procedures, serves as an excellent reference guide for materials scientists working on a wide variety of projects. I highly recommend this book to professionals and students as there is a wealth of knowledge made available to those wishing to launch their career within this discipline."
