Plastics: Materials and ProcessingAlthough most introductory texts on plastics focus on either materials or on processing, this book discusses the full range of materials, processes, and performance of plastics. This well-structured approach examines materials and the effects of processing from the molecular, micro, and macro levels. While providing a fundamental overview of a broad spectrum of topics, the text's high level of detail makes it valuable as both an introductory text and a professional reference manual. This detail is accomplished without extensive mathematics, so the book can be used by technicians, plastics professionals, and engineers. The book is useful for readers who may want to acquire, improve, or refresh their knowledge of plastic materials and processing. |
