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.

This report outlines the key issues regarding emissions from plastics. The report covers emissions from plastics during processing, treatment, storage and end-use. It summarises the published research on a wide variety of materials and settings. New methods of analysis and testing have been developed or adapted to examine these emissions. This report discusses the main techniques used. Data from analysis work on air quality and emissions from plastics is also included in this report. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

This report reviews sheet and profile extrusion, wire and cable coating and co-injection, describing both the rheological and structural considerations and the design and selection of machinery. Problems of layer instability and the c094 of layer c098 are addressed, as well as the selection of polymers and the recyclability of coextruded scrap. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

A very important factor in obtaining optimised physical properties from a semi-crystalline polymer is the size of the crystalline structures present in the material, and this crucially depends on the initiation process of crystallisation of the polymer from the melt - nucleation. This review provides information on the development of materials and methods for influencing the nucleation of polymer crystallisation in commercial processing by means of addition of low levels of adjuvants specifically selected for this purpose.

This report presents an overview of the chemical analysis of thermosets. Materials based on thermosets present the analyst with considerable challenges due to their complexity and the wide range of polymer types and additives available. This review sets out to present an introduction to the analytical techniques and methods that are used to characterise and carry out quality control work on thermosets, investigate the failure of thermosets products and to deformulate thermoset compounds. The review is accompanied by around 400 abstracts from papers and books in the Rapra Polymer Library database, to facilitate further reading on this subject.
Rubber Injection Moulding

This review has been written as a practical guide to rubber injection moulding. Many injection moulding processes produce rejects or scrap, because they depend on a b257 of variables. To eliminate waste it is necessary to learn how to recognise the variables that cause problems, and then experiment to understand their interdependence. This can be developed to a fine art and lead towards 'right first time' processing, the commercial ideal. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
