There is an exciting mix in these proceedings from both material suppliers and end users, who have discussed test and formulation data. There is an overview paper on the markets for rubbers from the International Rubber Study Group. There is also a new presentation on studies of food contact applications of high performance elastomers, with migration data available.
The objective of this Rapra Review Report is to provide a comprehensive overview of the use of rubber as a food contact material, from an initial description of the types of rubber which are used in the industry, through the formulation of products, and the contact regulations and migration testing regimes, to the research that is on-going to improve its safety and the trends for the future. This report is a completely revised and updated version of Rapra Review Report 119 published in 2000. This Rapra Review Report comprises a concise, expert review, supported by an extensive bibliography compiled from the Rapra Abstracts database on the topic of rubbers in contact with food. This bibliography provides useful additional information on this topical field.
Food and beverages can be very aggressive chemical milieu and may interact strongly with materials that they touch. Whenever food is placed in contact with another substance, there is a risk that chemicals from the contact material may migrate into the food. These chemicals may be harmful if ingested in large quantities, or impart a taint or odour to the food, negatively affecting food quality. Food packaging is the most obvious example of a food contact material. As the demand for pre-packaged foods increases, so might the potential risk to consumers from the release of chemicals into the food product. Chemical migration and food contact materials reviews the latest controls and research in this field and how they can be used to ensure that food is safe to eat.Part one discusses the regulation and quality control of chemical migration into food. Part two reviews the latest developments in areas such as exposure estimation and analysis of food contact materials. The final part contains specific chapters on major food contact materials and packaging types, such as recycled plastics, metals, paper and board, multi-layer packaging and intelligent packaging.With its distinguished editors and international team of authors, Chemical migration and food contact materials is an essential reference for scientists and professionals in food packaging manufacture and food processing, as well as all those concerned with assessing the safety of food. - Reviews worldwide regulation of food contact materials - Includes the latest developments in the analysis of food contact materials - Looks in detail at different food contact materials
Fluoropolymers were discovered accidentally by Plunkett in 1938. He was working on freon and accidentally polymerised tetrafluoroethylene. The result was polytetrafluoroethylene (PTFE), more commonly known as Teflon. PTFE is inert to virtually all chemicals and is considered to be the most slippery material in existence - it has the lowest coefficient of friction of any known solid material. These properties have made it one of the most valuable and versatile technologies ever invented, contributing to significant advancements in areas such as aerospace, communications, electronics, industrial.
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.
High performance plastics are replacing traditional materials in hostile environments. They possess characteristics such as exceptional strength, lightweight, temperature resistance (usually in excess of 160°C), chemical resistance and dimensional stability. In addition, plastics are relatively easy to process and can be coloured (or transparent) and moulded to create innovative and attractive structures. The fun car market illustrates the increasing use of plastics materials and the versatility and appeal needed in materials for today's marketplace. This two day international conference brought together experts discussing the latest developments in materials including properties, processing and applications.There are many different types of high performance elastomers. Their unique properties are essential in hostile environments and application areas include the petrochemical and refining industries, automotive, aerospace, defence, wire and cable, construction, chemical plants, nuclear, medical, food and seals. Correct material selection, compounding and processing are essential. These proceedings have brought together a collection of papers for material suppliers, engineers, compounders, manufacturers, processors and end-users of high performance elastomers who discussed the most appropriate materials and formulations for different applications.
This book is the definitive reference source for professionals involved in the conception, design and specification stages of a construction project. The theory and practical aspects of each material is covered, with an emphasis being placed on properties and appropriate use, enabling broader, deeper understanding of each material leading to greater confidence in their application. Containing fifty chapters written by subject specialists, Construction Materials Reference Book covers the wide range of materials that are encountered in the construction process, from traditional materials such as stone through masonry and steel to advanced plastics and composites. With increased significance being placed on broader environmental issues, issues of whole life cost and sustainability are covered, along with health and safety aspects of both use and installation.
