Rubber Analysis

This review outlines each technique used in rubber analysis and then illustrates which methods are applied to determine which facts. This d104 is a good introduction to a very complex subject area and will enable the reader to understand the basic concepts of rubber analysis. Around 350 abstracts from the Rapra Polymer Library database accompany this review, to facilitate further reading. These include core original references together with abstracts from some of the latest papers on rubber analysis.

The first edition of this book (1958) described an analytical situation which had existed for a number of years for maintaining quality control on vulcanizates of natural rubber although the situation had recently been disturbed by the introduction of a range of synthetic rubbers which required identification and quantitative estimation. For the former purpose 'wet' chemistry, based on various imperfectly understood organic reactions, was pressed into service. Alongside this was the first introduction of instrumental analysis, using the infrared spectra of either the polymers or, more usually, their pyrolytic products to 'fingerprint' the material. The identification of a range of organic accelerators, antioxidants and their derivatives which had been intro duced during the 1920s and 30s was, in the first edition, dealt with by a combination of column chromatography and infrared spectroscopy or by paper chromatography. Quantitative procedures were, however, still classical in the tradition of gravimetric or volumetric assays with an initially weighed sample yielding, after chemical manipulation, a carefully precipitated, dried and weighed end product, or a solution of known composition whose weight or titre, as a percentage of the initial sample, quantified the function being determined. The second edition of this work (1968) consolidated the newer techni ques which had been introduced in the first without adding to them although, in other applications of analytical chemistry, instrumental analysis had already brought about a transformation in laboratory practice.

Rubber analysis plays a vital part in ensuring that manufactured products are fit for purpose. This comprehensive, application-based book with up-to-date referencing covers all important applications and subject area associated with the analysis of rubber compounds and rubber products. Includes characterization of rubber polymers, rubber fumes, identification of extractables and leachables, as well as reverse engineering on compounded products.

As a result of recent political reforms, Myanmar has the opportunity to enact major policy changes to reinvigorate its agriculture sector. In this context, Myanmar’s rubber sector has the potential to become an even greater source of export earnings and rural household incomes, but there are major challenges related to low rubber productivity and poor rubber quality. Using data from the Mon State Rural Household Survey (MSRHS) conducted from May to June 2015, as well as qualitative data collected from rubber producer focus groups and other interviews with rubber producers, traders, and processors, this paper describes the cost structure of rubber production in Mon State. We then estimate smallholder production costs and the profitability of smallholder rubber production under various alternative yield and price scenarios. The results suggest that if the weaknesses hindering the profitability of the rubber sector are not addressed, the rubber sector will likely stagnate. Moreover, in the absence of a major increase in world prices (substantially above the 2000–2016 average), new rubber investments will not be profitable without major improvements in yield and quality. Further, increasing only yields or only quality, or only improving the institutional environment, will not result in positive returns on investment for smallholders; reforms are needed in all three areas. If these weaknesses are addressed, however, Myanmar’s new investments will be profitable and Myanmar could become an important rubber producer and exporter on the world stage.

Anticorrosive Rubber Lining discusses the state-of-the-art in this evolving industry, including sections on the best materials and formulations to use, what's best for a particular application, which repair technique is best for a given application, how long a rubber lining is likely to last, vulcanization parameters, and more. This book deals with the important field of anticorrosive rubber lining and its applications in various industries, including oil and gas, nuclear, aerospace, maritime, and many more, highlighting many of the technological aspects involved. The author offers a unique perspective due to the exclusiveness of the case histories presented, including many industrial rubber lining practices which are mostly kept within the industry. The technical information on rubber presented here is a practical tool to enable engineers to make the best use of rubber linings to prevent corrosion in chemical plants. The book includes valuable insights into bonding systems, surface preparation, and coating methodologies, and also covers failure analysis of failed systems. Includes up-to-date technical information on special compounding and processing technology of recently developed synthetic rubbers Provides detailed case studies from industry sectors, including aerospace, nuclear energy, and mining Presents rare, valuable insider knowledge of current industry practice
