Pvc Technology

This book continues the tradition of the first two editions of the late W. S. Penn's original PVC Technology, and the extensively revised third (1971) edition prepared by myself and B. J. Lanham. In the present edition the original general format, and the arrange ment of chapters, have been largely preserved, but virtually nothing now remains of Penn's own text: a part of the contents is based on material from the 1971 TitowlLanham version (revised, updated and mainly rewritten): the rest is new, including, inter alia, several chapters specially contributed by experts from the plastics industry in the UK and Europe. The section listing international (ISO) and national (BS, ASTM and DIN) standards relevant to PVC, which was first intro duced (as Appendix 1) in the 1971 edition, proved a popularfeature: it has now been brought up to date and considerably extended. Two further appendices provide, respectively, comprehensive unit conver sion"tables (with additional information on some ofthe mostfrequently encountered units, and the SI units), and a list of many properties of interest in PVC materials, with definitions, typical numerical values, and references~to relevant standard test methods. For various reasons, work on this edition involved more than the usual quota of problems: I am truly grateful to the Publisher's Manag ing Editor, Mr G. B. Olley, for his understanding, patience, unfailing courtesy and friendly encouragement.

This report reviews the composition and synthesis of PVC, composition and formulation technology, compounding and manufacturing technology, and the additional range of materials made possible by blending with other polymers. It is completed by around 500 abstracts selected from the Rapra Polymer Library database.

Revised and updated throughout, this second edition covers significant changes and advances in PVC science and technology.;Volume 3 examines such diverse subjects as: PVC compounding equipment, compounding process control, solid and liquid compound process development, compound and product specifications, test methods with an interpretation of test results, environmental and occupational safety, and melt processing.;Providing over 700 literature references, volume 3 is intended for polymer, plastics, physical, organic, surface, and colloid chemists; plastics, chemical, materials, mechanical, and manufacturing engineers and technical personnel; and graduate and postgraduate students in these disciplines.

This book originated from my Publisher's request for anew, concise account of PVC plastics in terms of their nature, properties, process ing, and applications. There is thus, inevitably, an extensive thematic overlap with my-still relatively recent-PVC Technology (4th edi tion), and I have drawn liberally on that source for a substantial amount of relevant basic material. However, the present book is by no means merely an abridgement of the earlier one: whilst indeed considerably shorter, it is not only comparable in scope and general coverage of the subject, but also contains much new information. I have made a point of again strongly featuring the numerous standards relevant-and in many cases cardinal-to the testing and characterisa tion of PVC materials and products, and to the evaluation of their properties and performance: these standards are an indispensable part of the technology of PVC plastics, and nobody concerned with any aspect of this complex subject should fail to recognise that fact. It is ever a pleasure to express appreciation and thanks where they are due. I am grateful to Dipl-Ing. H. E. Luben of Brabender OHG, Duisburg, FRG, not only for the up-to-date information he provided on Brabender equipment, but also most particularly for his exception ally friendly, helpful attitude in all our contacts, and for the trouble he took to make some illustrations and figures available in the form convenient for direct reproduction.
