Book excerpt: After price and delivery time, the most frequently asked question about a product is 'How long will it last?' Lifetime expectancy is often many years, the service conditions may be complex, and there is a scarcity of definitive data on durability. The situation is complicated by the fact that there are a vast number of degradation agents, service conditions, properties of importance and different plastics. There are many inherent difficulties in designing durability tests. In many cases, the time scale involved is such that accelerated test conditions are essential. Whilst large amounts of durability data are generated by accelerated methods, much of it is only useful for quality control purposes and relatively little has been validated as being realistically capable of representing service. Most assessments of the lifetime of plastics are made by considering some measure of performance, such as impact strength, and specifying some lower limit for the property, which is taken as the end point. Lifetime is not necessarily measured in time. For example, for some products it will be thought of as the number of cycles of use. The object of this publication is to provide practical guidance on assessing the useful service life of plastics. It describes test procedures and extrapolation techniques together with the inherent limitations and problems. The Guide aims to make available the wealth of information that can be applied to help maximise the effectiveness of a durability-testing programme. This guide seeks to be comprehensive but concentrates on the most common environmental effects causing degradation. The test procedures used are outlined and the relevant textbooks and international standards are well referenced. Examples of lifetime testing studies are cited. The Practical Guide will be useful for anyone responsible for designing, manufacturing or testing plastic components. It will also be of benefit to suppliers and users of end products, as assessment of useful lifetime is critical to the economics and safety aspects of any component. Key features Test methods outlined Accelerated testing discussed Prediction methods described Standards cited Key sources of information listed

Available in PDF, EPUB and Kindle. Book excerpt: This book covers material challenges and technology innovation in coated and laminated textiles for aerostats and airships. Aerostats/airships are lighter-than-air (LTA) aircraft which are generally used in defence applications and face many harsh environmental conditions. For sustaining such conditions, there are special requirements for the material to be used in aerostats/airships which generally include a multi-layered coated/laminated textile using a textile fabric in base layer and different polymers for coating/lamination. Therefore, this book covers typical materials developed by different countries, challenges for developing material for aerostat/airship envelope and the future scope. Features: Exclusive title on materials used for LTA envelopes. Discusses material challenges such as selection of suitable fibre, polymer, additive, coating/lamination techniques, joint type and sealing techniques. Includes typical materials developed by different companies and researchers worldwide. Clearly explains technical concepts using figures, schemes and tabulated data. Includes case studies on material developed for aerostats/airships by different countries including NASA, Lockheed Martin, JAXA, ADRDE and DRDO. This book is aimed at graduate students, researchers and professionals in textiles engineering and aerospace engineering.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Polyvinyl chloride (PVC) has been around since the late part of the 19th century, although it was not produced commercially until the 1920s; it is the second largest consumed plastic material after polyethylene. PVC products can be rigid or flexible, opaque or transparent, coloured, and insulating or conducting. There is not just one PVC but a whole family of products tailor-made to suit the needs of each application. PVC is extremely cost effective in comparison to other plastics with a high degree of versatility in end-use and processing possibilities, as the reader will note from this book. It is durable, easily maintained, and can be produced in a large range of colours. As a result PVC finds use in an extensive range of applications in virtually all areas of human activity, including medical equipment, construction applications such as flexible roof membranes, pipes and window profiles, toys, automotive parts and electrical cabling. The PVC industry has also started to tackle some of its end-of-life issues. This practical guide provides comprehensive background on the resins and additives, their properties and processing characteristics, as well as discussion of product design and development issues. There have been, and still are, issues and perceptions over environmental and health acceptance covering vinyl chloride monomer, dioxins, phthalate plasticisers, and lead (and cadmium) based heat stabilisers and these are discussed in depth in this book. This book will be of interest to raw materials suppliers and processors or end-users of PVC, as well as anyone with a general interest in this versatile material: resins and additives properties and testing design issues processing, including post processing and assembly property enhancement sustainable development

Available in PDF, EPUB and Kindle. Book excerpt: A Practical Guide to Plastics Sustainability: Concept, Solutions, and Implementation is a groundbreaking reference work offering a broad, detailed and highly practical vision of the complex concept of sustainability in plastics. The book's aim is to present a range of potential pathways towards more sustainable plastics parts and products, enabling the reader to further integrate the idea of sustainability into their design process. It begins by introducing the context and concept of sustainability, discussing perceptions, drivers of change, key factors, and environmental issues, before presenting a detailed outline of the current situation with types of plastics, processing, and opportunities for improved sustainability. Subsequent chapters focus on the different possibilities for improved sustainability, offering a step-by-step technical approach to areas including design, properties, renewable plastics, and recycling and re-use. Each of these pillars are supported by data, examples, analysis and best practice guidance. Finally, the latest developments and future possibilities are considered. Approaches the idea of sustainability from numerous angles, offering practical solutions to improve sustainability in the development of plastic components and products Explains how sustainability can be applied across plastics design, materials selection, processing, and end of life, all set alongside socioeconomic factors Considers key areas of innovation, such as eco-design, novel opportunities for recycling or re-use, bio-based polymers and new technologies
