Book excerpt: The properties of rubbers are subject to change as a result of ageing, ultimately to the point where the material is no longer capable of fulfilling its function. In many applications, the longevity of rubber components is of critical importance. During its lifetime a rubber may be subjected to a variety of exposure conditions leading to different types of degradation. After a brief introduction to the main environmental and mechanical factors affecting performance, the authors of this Rapra Review Report focus on the thermo-oxidative ageing of rubber. As the lifetime for some products is meas.

Book Synopsis Service Life Prediction of Polymers and Plastics Exposed to Outdoor Weathering by : Christopher White
Download or read book Service Life Prediction of Polymers and Plastics Exposed to Outdoor Weathering written by Christopher White and published by William Andrew. This book was released on 2017-10-13 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Service Life Prediction of Polymers and Plastics Exposed to Outdoor Weathering discusses plastics and polymers and their unique applications, from sealants used in construction, to polymer composites used in planes. While these materials are important enablers for advanced technologies, exposure to weather changes the very properties of plastics that make them so useful. This book reviews current research needs and provides a consensus roadmap of the scientific barriers to validated predictive models for the response of polymers and plastics to outdoor exposure. Despite extensive efforts over the past 20-30 years, testing of polymeric materials in accelerated or natural weathering conditions and the interpretation of the weathering results still require substantial improvements. This book represents the state-of-the-art in the prediction techniques available and in development. Engineers and materials scientists working in this field will be able to use the content of this book to assess the strengths and challenges of a range of different methods and approaches. Enables engineers and scientists in a range of industries to more successfully predict the durability of polymers, paints and coatings when exposed to weather Provides the latest information to help determine the sustainability of polymeric materials Reviews the current state-of-the-art in this area and identifies research needs that are followed by more detailed discussions of specific polymers and applications
Book Synopsis Physical Testing of Rubber by : Roger Brown
Download or read book Physical Testing of Rubber written by Roger Brown and published by Springer Science & Business Media. This book was released on 2006-03-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rubber is important in many engineering applications because of its unique properties. These properties must be measured with appropriate test methods developed specifically for this class of materials. This book provides, in one volume, comprehensive coverage of the procedures for measuring the whole range of the physical properties of rubber. This new edition presents an up-to-date introduction to the standard methods used for testing, quality control analysis, product evaluation, and production of design data for rubber and elastomers. Factors to be incorporated in the revision include the effects of newer instrumentation, the cutting back of laboratory staff, increased demands for formal accreditation and calibration, trend to product testing, overlap of thermoplastic elastomers with plastics and increased need for design data.

Available in PDF, EPUB and Kindle. Book excerpt: This report provides an excellent, clearly written report on the state-of-the-art of food contact elastomers. In the UK, the Ministry of Agriculture Fisheries and Food (MAFF), industry and Rapra have combined forces to study the issues surrounding rubbers in contact with food. A survey has been carried out of the food processing industry to determine which rubber products come into contact with food, contact area, duration of contact and temperature of contact. The results of this survey are found in the report and a compilation of data tables on each food industry studied is included as an appendix. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

Book Synopsis Natural Ageing of Rubber by : Roger P. Brown
Download or read book Natural Ageing of Rubber written by Roger P. Brown and published by iSmithers Rapra Publishing. This book was released on 2000 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique collection of long term ageing data, available for the first time, from Rapra Technology Limited. This report is an output from the Weathering of Elastomers and Sealants project which forms part of the UK government's Department of Trade and Industry's Degradation of Materials in Aggressive Environments Programme. Rapra Technology Limited has just completed a comprehensive natural ageing and physical testing programme on 19 rubber compounds, stored in controlled conditions, for a period of 40 years. This is believed to be the most extensive such study ever carried out. Now, for the first time, all the results of this unique programme have been published in this report. The properties of natural and synthetic rubbers suit them to a diverse range of applications, many of which demand a prolonged service life, and the retention of some or all of their mechanical properties for years or even decades. When the ageing programme was conceived in the 1950s, rubber product manufacturers were faced with a wider range of raw rubbers than had ever been available before. The relatively recent development of some of these materials also meant that there was little information available regarding their longevity. Thus the need was identified for a systematic programme of storage and testing. Rubber formulations were selected to represent those used in a wide range of applications, including general purpose and 'good ageing' grades. The results of all these tests are presented graphically in this report, allowing the rate of deterioration of properties and the influence of the environment to be clearly seen. Properties after 40 years are also tabulated, together with calculationsof percentage change. This information wi

Book Synopsis Physical Test Methods for Elastomers by : Roger Brown
Download or read book Physical Test Methods for Elastomers written by Roger Brown and published by Springer. This book was released on 2017-10-18 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive coverage of all aspects of physical testing of elastomers (rubbers and thermoplastic elastomers) including mechanical, electrical, thermal and all aspects of durability. Elastomers are an important class of materials used in such products as tyres, seals and hose which have markedly different properties to other materials. The importance of testing of elastomers means that a comprehensive text on the subject is essential. The advantage over general materials testing books is being more specific while the advantage over general rubber technology books is that testing is dealt with in depth.
