Long-Term and Accelerated Ageing Tests on Rubbers by Roger P. Brown,M. J. Forrest Pdf

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. After a brief introduction to the main environmental and mechanical factors affecting performance, this review focuses on the thermo-oxidative ageing of rubber. It considers the methods of, and the published results from, both natural and accelerated tests. A major section of the report is devoted to exposure and test techniques with discussion of the methods of physical and chemical analysis. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

Long-term and Accelerated Ageing Tests on Rubbers by Roger P. Brown Pdf

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.

Ageing of Rubber by Roger P. Brown,T. Butler,S. W. Hawley Pdf

Annotation This report details the results of accelerated heat ageing studies undertaken on re-mixed samples of those materials studied for the natural ageing study and on the 20 new compounds chosen to represent polymers not available in 1958 and to reflect changes in compounding practice. In addition to those properties studied for the artificial weathering exposures compression set and dynamic properties were also measured.

Elastomers and Components by V A Coveney Pdf

Elastomeric components are widely used in engineering. Increasing demands are placed on them to withstand hostile conditions such as high temperature and corrosive environments. These demands make it harder to predict likely service life or improve design to ensure their longer-term performance. This important book reviews the wealth of research on understanding fatigue and failure in elastomers, and how this understanding can be used to predict and extend their service life.The first part of the book reviews factors determining ageing behaviour such as heat, corrosive environments, wear and cracking. It also discusses the strengths and weaknesses of current service prediction models. The second part of the book focuses on analysing and improving the design and service life of particular applications such as O-rings, bearings, springs and valves.With its distinguished editor and team of contributors, Elastomers and components: service life prediction; progress and challenges is an invaluable reference for engineers involved in the design and use of elastomers. Looks at the wealth of research on understanding fatigue and failure in elastomers Discusses the strengths and weaknesses of current service prediction models An invaluable reference for engineers

Physical Testing of Rubber by R.P. Brown Pdf

Physical testing of Rubber is an essential reference for anyone concerned with evaluating rubber materials or with using material property data for design. There is much new and updated material, due to improvements made to apparatus by the introduction of advanced instrumentation and automation, and many changes in international standards. A number of subjects common to all areas of physical testing are addressed. These include discussion of the reasons for testing, the trends in test development, the use of statistics and quality control of laboratories.

Ageing of Rubber by Roger P. Brown,T. Butler,S. W. Hawley Pdf

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. A long-term natural ageing programme was started in 1958 when 19 rubber compounds were exposed at 3 locations. The final sets of test pieces were withdrawn in 1998 giving a total of 40 years of natural ageing. The results of the physical tests carried out at intervals over the period were published in 2000 by Rapra in 'Natural Ageing of Rubber?Changes in Physical Properties over.

Physical Testing of Rubber by Roger Brown Pdf

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.

Practical Guide to the Assessment of the Useful Life of Rubbers by Roger P. Brown Pdf

The object of this publication is to provide practical guidance on assessing the useful service life of rubbers. It describes test procedures and extrapolation techniques together with the inherent limitations and problems. This Guide seeks to be comprehensive but concentrates on the most common environmental effects causing degradation and the most important mechanical properties of rubbers. The test procedures used are outlined and the relevant d104books and International standards are referenced.

Physical Test Methods for Elastomers by Roger Brown Pdf

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.

Rubbers in Contact with Food by J.A. Sidwell,M.J. Forrest Pdf

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.
