Arburg practical guide to injection moulding / par Goodship,, V. Publication : [S.l.] : Smithers Rapra Press, 2004 . 276 p. ; , This Practical Guide to Injection Moulding is based on course material used by ARBURG in training operators of injection moulding machines. It comes from many years of experience in this field and has been edited by an expert injection moulder at Warwick University. It will be of use to experts looking to fill gaps in their knowledge base and to those new to the industry. The factors involved in injection moulding, from material properties and selection to troubleshooting faults, are all examined in this book. It covers the equipment types in use and machine settings for different types of plastics. Material flow is critical in moulding and there are sections covering rheology and viscosity. High temperature can lead to poor quality mouldings due to material degradation and this is discussed. There are an exceptional number of figures in this text, with many photographs of machinery and mouldings to illustrate key points. There are also numerous tables listing key properties and processing parameters. Flow charts are included in the chapter on troubleshooting to indicate what can be changed to resolve common problems. Injection moulding in the Western World is becoming increasingly competitive as the manufacturing base for many plastics materials has moved to the East. Thus Western manufacturers have moved into more technically difficult products and mouldings to provide more added value and maintain market share. Technology is becoming more critical, together with innovation and quality control. There is a chapter on advanced processing in injection moulding covering multi-material and assisted moulding technologies. This Guide will assist progress in developing good technical skills and appropriate processing techniques for the range of plastics and products in the marketplace. 30 cm.

Biodegradable polymers market report par Platt , David K. Publication : UK Smithers Rapra Press 2006 . 166 p. , Biodegradable polymers have experienced strong growth over the last three years and are set to make further inroads into markets traditionally dominated by conventional thermoplastics in future. Demand is being driven by a number of factors. The cost of biodegradable polymers has come down considerably over the last three years while at the same time standard thermoplastic prices have increased considerably. Now, some classes of biodegradable polymers are price competitive with polymers such as PET. The biodegradable polymers industry itself has established an agreed framework for testing and certification and there is growing political pressure in developed countries to reduce packaging waste and develop a composting infrastructure. Biodegradable polymer producers have also invested in product and process improvements. Finally, consumers and brand owners are beginning to recognise the benefits of sustainable or 'green' packaging. Four main classes of biodegradable polymers are analysed in this report, polylactic acid (PLA), starch-based polymers, synthetic biodegradable polymers, such as aromatic aliphatic co-polyesters, and polyhydroxyalkanoates (PHA). The report analyses their key performance properties, applications development, market drivers and future prospects. Each product section also contains an estimate of market size by world region and end use market, plus forecasts to 2010. There is also an analysis of key suppliers and their products. Key Features: Biodegradable polymers market size by geographic region, polymer type and end use sector, 2000 and 2005, plus forecasts to 2010. Market opportunity analysis by end use sector, such as packaging, bags and sacks, foodservice, agriculture, medical, consumer products and fibres. Illustrations of product and applications development over the last three years. Supply chain analysis: including details of thirty leading biodegradable polymer suppliers and profiles of around fifty of the world's leading biodegradable polymer processors. Analysis of biodegradable polymer performance properties, market drivers, applications and product developments. 30 cm.

Handbook of biodegradable polymers / par Bastioli,, C. Publication : [Shawbury] Smithers Rapra Press 2005 . 552 p. , Biodegradable polymers are niche market materials finding focused applications, including agricultural applications such as mulch films, flowerpots and controlled-release fertilisers and packaging items such as carrier bags and food wrapping and containers. They have the potential to provide a solution to a range of environmental concerns: decreasing availability of landfill space, declining petrochemical sources, and also offer an alternative option to recycling. Rapra's Handbook of Biodegradable Polymers is a complete guide to the subject of biodegradable polymers and is ideal for those new to the subject or those wanting to supplement their existing knowledge. The book covers the mechanisms of degradation in various environments, by both biological and non-biological means, and the methods for measuring biodegradation. The degree and rate of biodegradation is dependent on the chemical composition of the polymer and its working environment, and so there is no single optimal method for determining biodegradation. This handbook provides discussion of international and national standards and certification procedures developed to ensure accurate communication of a material's biodegradability between producers, authorities and consumers. The book goes on to consider the characteristics, processability and application areas for biodegradable polymers, with key polymer family groups discussed. 25 cm.

Polymer reference book par Crompton, TR. Publication : [S.l.] Smithers Rapra Press 2006 . 722 p. , The aim of the Polymer Reference Book is to familiarise the reader with all aspects of the techniques used in the examination of polymers, including chemical, physico-chemical and purely physical methods of examination. This book describes the types of techniques now available to the polymer chemist and technician, and discusses their capabilities, limitations and applications. All types of modern instrumentation are covered including those used in general quality control, research analysis, process monitoring and for determining the mechanical, electrical, thermal and optical characteristics. Aspects such as automated analysis and computerised control of instruments are also included. The book covers not only instrumentation for the determination of metals, non metals, functional groups, polymer structural analysis and end-groups in the main types of polymers now in use commercially, but also the analysis of minor non-polymeric components of the polymer formulation, whether they be deliberately added, such as processing additives, or whether they occur adventitiously, such as residual volatiles and monomers and water. Fingerprinting techniques for the rapid identification of polymers and methods for the examination of polymer surfaces and polymer defects are also discussed. The book gives an up-to-date and thorough exposition of the present state-of-the-art of the theory and availability of instrumentation needed to effect chemical and physical analysis of polymers. Over 1,800 references are included. The book should be of great interest to all those who are engaged in the examination of polymers in industry, university research establishments and general education. The book is intended for all staff who are concerned with instrumentation in the polymer laboratory, including laboratory designers, work planners, chemists, engineers, chemical engineers and those concerned with the implementation of specifications and process control. 25 cm.
