Pages : 352 pages

No book has been published that gives a detailed description of all the types of plastic materials used in medical devices, the unique requirements that the materials need to comply with and the ways standard plastics can be modified to meet such needs. This book will start with an introduction to medical devices, their classification and some of the regulations (both US and global) that affect their design, production and sale. A couple of chapters will focus on all the requirements that plastics need to meet for medical device applications. The subsequent chapters describe the various types of plastic materials, their properties profiles, the advantages and disadvantages for medical device applications, the techniques by which their properties can be enhanced, and real-world examples of their use. Comparative tables will allow readers to find the right classes of materials suitable for their applications or new product development needs.

This chapter focuses on adhesives used in direct physiological contact in dental and medical procedures. Activity in both areas has been quite extensive outside the United States for decades. In contrast, adhesive use in medical devices, patches, and plasters has been ongoing in the United States for a long time. In the case of medical devices, adhesion is concerned with the joining of materials such as plastics, elastomers, textiles, metals, and ceramics, which are examined in other chapters of the present volume and are covered in various references [1–6], The coverage of this chapter is devoted to applications where to adhesives are in direct contact with tissues and other live organs.

The use of plastics is widespread. Less widespread, however, is a clear understanding and examination of the many forms of degradation inherent within the very environments these materials must perform. Medical PlasticsùDegradation Resistance & Failure Analysis fills that void. The introductory chapter gives an overview of the medical applications of plastics and the specific performance requirements they need to meet. The following chapters discuss various degrading environments and their effects including environmental stress cracking, effect of body liquids, effect of harsh environments, and various methods of sterilization. The book also discusses the failure of medical devices due to contamination, low temperature, the effects of UV light, migration of formulation components, mechanical stresses, and problems with design and fabrication. Case histories of failures of some common products used in medicine are also provided.

Pages : 302 pages

Emerging Trends in Medical Plastic Engineering and Manufacturing gives engineers and materials scientists working in the field detailed insights into upcoming technologies in medical polymers. While plastic manufacturing combines the possibility of mass production and wide design variability, there are still opportunities within the plastic engineering field which have not been fully adopted in the medical industry. In addition, there are numerous additional challenges related to the development of products for this industry, such as ensuring tolerance to disinfection, biocompatibility, selecting compliant additives for processing, and more. This book enables product designers, polymer processing engineers, and manufacturing engineers to take advantage of the numerous upcoming developments in medical plastics, such as autoregulated volume-correction to achieve zero defect production or the development of ‘intelligent’ single use plastic products, and methods for sterile manufacturing which reduce the need for subsequent sterilization processes. Finally, as medical devices get smaller, the book discusses the challenges posed by miniaturization for injection molders, how to respond to these challenges, and the rapidly advancing prototyping technologies. Provides a roadmap to the emerging technologies for polymers in the medical device industry, including coverage of ‘intelligent’ single use products, personalized medical devices, and the integration of manufacturing steps to improve workflows Helps engineers in the biomedical and medical devices industries to navigate and anticipate the special requirements of this field with relation to biocompatibility, sterilization methods, and government regulations Presents tactics readers can use to take advantage of rapid prototyping technologies, such as 3D printing, to reduce defects in production and develop products that enable entirely new treatment possibilities

Publisher : William Andrew
Release Date : 2013-11-28
ISBN 10 : 1455731099
Pages : 800 pages

Thermosetting plastics are a distinct category of plastics whose high performance, durability and reliability at high temperatures makes them suitable for specialty applications ranging from automotive and aerospace through to electronic packaging and consumer products (your melamine kitchen worktop is a thermoset resin!). Recent developments in thermoset plastics technology and processes has broadened their use exponentially over recent years, and these developments continue: in November 2011, French scientists created a new lightweight thermoset that is as strong and stable as previous materials yet can be easily reworked and reshaped when heated which makes it unique amongst thermosets and allows for repair and recycling. The Handbook of Thermoset Plastics, now in its 3rd edition, provides a comprehensive survey of the chemical processes, manufacturing techniques and design properties of each polymer, along with their applications. Written by a team of highly experienced practitioners, the practical implications of using thermoset plastics are presented – both their strengths and weaknesses. The data and descriptions presented here enable engineers, scientists and technicians to form judgments and take action on the basis of informed analysis. The aim of the book is to help the reader to make the right decision and take the correct action – avoiding the pitfalls the authors’ experience has uncovered. The new edition has been updated throughout to reflect current practice in manufacturing and processing, featuring: Case Studies to demonstrate how particular properties make different polymers suitable for different applications, as well as covering end-use and safety considerations. A new chapter on using nanoparticles to enhance thermal and mechanical properties. A new chapter describing new materials based on renewable resources (such as soy-based thermoset plastics). A new chapter covering recent developments and potential future technologies such as new catalysts for Controlled Radical Polymerization. Goodman and Dodiuk-Kenig provide a comprehensive reference guide to the chemistry, manufacturing and applications of thermosets. Updated to include recent developments in manufacturing – from biopolymers to nanocomposites. Case Studies illustrate applications of key thermoset plastics.
