This extensively revised and updated second edition of the only data handbook available on the engineering properties of commercial polymeric films details many physical, mechanical, optical, electrical, and permeation properties within the context of specific test parameters, providing a ready reference for comparing materials in the same family as well as materials in different families. Data are presented on the characteristics of 47 major plastic and elastomer packaging materials. New to this edition, the resin chapters each contain textual summary information including category, general description, processing methods, applications, and other facts as appropriate, such as reliability, weatherability, and regulatory approval considerations for use in food and medical packaging. Extensive references are provided. The resin chapter material supplier trade name product data are presented in graphical and tabular format, with results normalized to SI units, retaining the familiar format of the 1st edition and allowing easy comparison between materials and test conditions.

Geosynthetics often play critical roles in civil engineering and it is important that the materials in use can withstand the physical and chemical pressures of the environment. These range from resistance to leachates from landfill to resistance to root damage in soil liners, as well as standard properties such as resistance to creep, oxidation and UV light, and tensile strength. This Rapra Review Report discusses the polymers used in each category of geosynthetics, production methods, test methods and applications. The review is accompanied by around 400 abstracts from papers and books in the Rapra Polymer Library database, to facilitate further reading on this subject.

The overall aim of this book is to aid the process of sourcing and selecting appropriate thermoplastic polymers. There are now a wide diversity of thermoplastics offered for commercial uses. At one end of the range are the high-volume commodity materials for short life consumer applications. Whereas at the other end are the high value engineering materials; with significant levels of mechanical, physical and electrical performance. Within this publication, the generic groups of thermoplastics can be identified, along with their respective attributes and limitations. All thermoplastics are available in different grades. The constituents selected to form a grade are chosen to modify aspects of material behaviour, both during processing and in the final moulded form. The directory addresses materials which can be obtained in granular, powder or paste form for subsequent processing. Information is not provided directly on semi-finished product forms, such as films, fibres, sheet or profiles, other than when inferred from the processing descriptions of specified grades. The directory covers virgin or compounded material. It does not specifically address reclaimed or recycled grades. Data is provided for the mechanical and physical properties of moulded grades as processed by the route intended by the primary manufacturer (M) or compounder (C). Material grades can be obtained from a number of sources; either the original polymer manufacturer or a recognised compounder who produces a range of grades.

Many people, including those involved in the manufacturing, marketing and selling of lubricants, believe that blending lubricants is simply a matter of putting one or more base oils and several additives into a tank of some kind and stirring them around to mix them. Blending lubricants that meet customers’ demands requires much more than this. The correct ingredients of the right quality need to be used in precisely controlled quantities. The ingredients need to be tested prior to blending and the finished products need to be tested following blending. The ingredients need to be stored and mixed under carefully controlled conditions. The finished lubricants need to be stored and packaged carefully and then delivered to customers correctly. This book discusses all of these issues, describes the different types of equipment used to blend lubricants, provides guidance on how best to use this equipment, and offers tips and techniques to help to avoid problems. It focuses on liquid lubricants. Greases are not discussed, as their manufacture involves very different manufacturing procedures compared with those concerned with liquid lubricants. The book starts with descriptions and discussion of the properties and characteristics of the main types of mineral and synthetic base oils, as well as the properties and characteristics of the main types of additives that are used in lubricant formulations. Criteria and methodologies used to design both new and upgraded blending plants are covered next. The types and operation of the equipment used in lubricant blending plants are described and discussed, together with a chapter on how to avoid problems before, during, and after blending. Testing and analysis of base oils, additives, and blended lubricants are covered in two separate chapters. Procedures for quality control and quality management in lubricant blending plants are also discussed in two separate chapters. Types of packages for lubricants are reviewed, together with methods for filling packages and methods for transporting lubricants in bulk. The storage of lubricants and supply chain management is also covered in depth.

High pressure technology is used so extensively that it is almost impossible to catalogue the manyways in which our lives are enhanced by it. From pneumatic tires and household water supplies tomaterials such as crystals, plastics, and even synthetic diamond, there are countless materialsfabricated or shaped using high pressure technology. High Pressure Technology (in two volumes)presents the most up-to-date information available on the main features of this broad technology andthe processes which utilize it.Volume I: Equipment Design, Materials, and Properties covers three broad areas: the general operationof high pressure systems, including standard operating procedures and safety codes and measures;the technology of high pressure systems, such as components, vessel design, and materials of construction;and applied science at high pressure, including the properties of fluids and solids andmechanical properties. Volume II: Applications and Processes covers processes at high pressure andencompasses such topics as: catalytic chemical synthesis; polymerization; phase changes; criticalphenomena; liquefaction of gases; synthesis of single-crystal materials, diamond, and superhardmaterials; isostatic compacting; isostatic hot-pressing; hydrostatic forming of metals; hydraulic cutting;and applications of shock techniques.Written by recognized authorities in industry, government laboratories, and universities, High PressureTechnology is essential reading for the industrial practitioner, high pressure engineer, and researchscientist. In addition, it is a valuable textbook for students in mechanical, chemical, and materialsengineering courses.
