This book is designed to introduce plastics to a wide range of readers who need to either gain, improve, or refresh their knowledge of plastic materials and manufacturing. It fully discusses both materials and manufacturing processes in a carefully-constructed and logical presentation. While providing a fundamental overview of a broad spectrum of topics, the author touches upon polymeric materials (molecular viewpoint), micro structures in polymers, mechanical properties (macro viewpoint), chemical and physical properties (macro viewpoint), thermoplastic materials (commodity plastics), thermoplastic materials (engineering plastics), thermoset materials, elastomeric (rubber) materials, designing with plastics, extrusion process, injection molding process, blow molding process, thermoforming process, rotational molding process, casting processes, foaming processes, compression and transfer molding processes, polymeric composite materials and processes, radiation processes, finishing and assembly, environmental aspects of plastics, and operations. For practicing engineering technologists and engineers as well as anyone interested in plastics.
