This report describes the current state of the art in mixing from a practical viewpoint. Developments that have taken place in mixing equipment over the last eight or nine years have been significant, with almost all major machinery makers having made innovations of one type or another. Some developments have been as small as re-profiling rotors of relatively conventional design. Others have been the introduction of completely new rotor designs, both intermeshing and tangential. This report begins by offering historical background against which the latest developments are set. It consider

"For many years, Smithers Rapra has carried out research projects for the UK Food Standards Agency (FSA). This review report has, as its origin, an FSA project on coatings and inks that was carried out at Smithers Rapra from 2005 until 2007. The objective of this project was to assess the potential for the migration of substances from coatings and inks that were used in food packaging applications. As a significant amount of work had already been carried out on coatings that were in direct contact with food (e.g., can coatings), a boundary was set that only coatings and inks in non-direct foo

Chemical control measures in the EU are soon to be dramatically revised, and this Rapra Review Report sets the scene by describing the key facts of the existing measures and the objectives of the future chemicals policy: REACH. REACH - Registration, Evaluation and Authorisation of Chemicals - will place a duty on companies that manufacture, import and use chemicals in the EU to assess the risks arising from their use and manage any risks identified. With industry concerns about the cost of compliance in terms of testing, in-house management, and scientific and regulatory advice and consultancy

A composite is defined as a combination of two or more materials with a distinguishable interface. The urge to improve the properties of composite materials, has prompted materials scientists to investigate composites with lower and lower reinforcement size, leading to the development of microcomposites and the recent trend in composite research is nanocomposites (with nanometer scale reinforcements). Polymer matrix composite (PMC) can be processed at a much lower temperature, compared to composites with other types of matrix. Depending on the types of polymer matrices, PMC are classified as t

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, industri

This review has been written as a practical approach to bonding various kinds of elastomers to substrates such as steel and plastics, as used in the manufacture of diverse products such as rubber covered rolls, urethane fork lift wheels, rubber lining for chemical storage or solid rocket motors, engine bushes and mounts, seals for transmissions, electrical power connectors and military tank track pads. There are over 20 kinds of elastomeric polymer each having unique physical and chemical resistance characteristics. Through compounding, a given elastomer’s performance can be enhanced bu
