Now in its Third Edition, Plastics is the key text for senior students studying the science and engineering of plastic materials. Starting from microstructure and physical properties, the book covers the mechanical, chemical and electrical properties of plastic materials, and also deals in detail with wider plastics issues that today consequently the case studies in chapter 14 were updated. A new chapter 15 introduces sport and biomaterials case studies, since increasing numbers of students are enrolled on courses with these emphases. The material has been thoroughly updated, and the principles of polymer structure-property relationships set out more clearly.
