Additives For Polyolefins

Additives for Polyolefins is a unique quick-reference resource for those who create or use polyethylene and polypropylene compounds—the most commercially important family of plastic materials, making up close to half of the volume all plastics produced and used. These polymers would be useless without various additives. The book focuses on polyolefin additives that are currently important in the plastics industry, alongside new additives of increasing interest, such as nanofillers and environmentally sustainable materials. As much as possible, each chapter emphasises the performance of the additives in the polymer, and the value each relevant additive brings to polypropylene or polyethylene. Where possible, similar additives are compared by capability and relative cost. In this new edition, product tables have been updated with the most current product and company names, new case studies have been added, the role of nanofillers is discussed in greater detail, and the book concludes with a discussion on blending and handling additives, along with an entirely new chapter on how engineers can approach the issue of sustainability when choosing an additive. Assesses capabilities and costs of a range of additives to enable engineers and scientists to make the correct selection for their property requirements Provides concise, practical information about the purpose and use of specific additives, fillers, and reinforcements – demystifying the world of additives by providing clear, engineering explanations, and including real-world application case stories Updated to include additional material on nanofillers, blending and handling, and sustainability

This book focuses on the polyolefin additives that are currently important in the plastics industry, alongside new additives of increasing interest, such as nanofillers and environmentally sustainable materials.

Where possible, similar additives are compared by capability and relative cost. With major sections for each additive function, this book provides a highly practical guide for engineers and scientists creating and using polyolefin compounds, who will find in this book a wealth of detail and practical guidance. This unique resource will enable them to make practical decisions about the use of the various additives, fillers, and reinforcements specific to this family of materials. ABOUT THE AUTHOR Michael Tolinski is a freelance writer and a lecturer at the University of Michigan's College of Engineering. He is a frequent contributor to Plastics Engineering and Manufacturing Engineering. Structured to make it easy for the reader to find solutions for specific property requirements Contains a number of short case studies about companies that have used or developed a particular additive to achieve a desired result Covers environmental resistance, mechanical property enhancement, appearance enhancement, processing aids, and other modifications of form and function

This review first discusses mould release and then addresses mould fouling. Significant material and process variables are considered first and then practical guidance on the selection of release agents and surface treatments are addressed. This is followed by advice on mould cleaning and the assessment of mould sticking and mould fouling. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

This book deals with the most important substances used as additives in the plastics industry to improve the properties of polymer-based materials. Each chapter deals with a particular type of additive based on the type's definition, structure, and classification according to main effects on polymeric materials. The mechanism of the additive efficiency and its effects on basic properties of specific polymers are discussed and a survey of its important qualities and practical applications is given. Each chapter is introduced by a theoretical analysis of the practical and technological importance of the ad ditive. The book is mainly intended for students in technical colleges, polytechnics and universities who are studying plastics technology and macromolecular chemistry as part of their general curriculum and for technologists in industry engaged in development, sales, technical service and production functions, and applications of plastics. An elementary knowledge of chemistry, physical chemistry and polymer science at the technical college level is assumed. Prague and Montreal, December 1982 J. Stepek, H.

Polyolefins are one of the most widely used commercial polymers. This book reviews the most important polyolefins, including polyethylene and polypropylene. These versatile fibres are durable, chemically resistant, lightweight, economical and functional. Polyolefin fibres: industrial and medical applications provides a comprehensive review of the structure and properties of this group of fibres, together with methods to improve the functionality of polyolefins and their range of applications. The first set of chapters discusses the different types of polyolefins, their structural and chemical properties as well as their production methods. The second group of chapters examines how to improve the functionality of polyolefin fibres. A final group of chapters addresses how polyolefins can be incorporated into specific applications such as industrial, medical and automotive products. Written by a distinguished team of international contributors, Polyolefin fibres: industrial and medical applications is a quintessential reference for textile technologists, fibre scientists, yarn and fabric manufacturers and also those in academia. Reviews the most important polyolefins including polyethylene and polyproplene, their structural and chemical properties as well as production methods Examines methods to improve the functionality of polyolefin fibres including production methods and quality control

In this first book on an additive group of growing importance, the authors review the commercial additives available on the market. The applications chapters provide you with a step by step description of techniques to select and incorporate these additives in various products. Engineers and scientits involved in polymer processing need practical information about these additives, their applications, and proper and safe handling. Until now much of this information has been difficult to obtain because of commercial secrecy. In recent years, the applications of fluoropolymer additives have expanded significantly, with even the meaning of ‘fluoropolymer additives’ expanding from relatively the narrow definition of PTFE powder fillers to a wide variety of fluoropolymer elastomers, used as a processing aid for plastics processing such as extrusion, injection molding, and film blowing. The benefits of fluoropolymer additives used in plastics are the elimination of sharkskin defects, increases in process speed and output (up to 20%), the reduction of die build up, the reduction of gels and optical defects, etc. In addition, fluropolymer additives are being increasingly used in inks, lubricants, and coatings. For example, in the coating industry fluoropolymer additives can increase the life cycle of exterior coatings due to their excellent weatherability and subsequently increase the time between recoats. Fluoropolymer additives are becoming more widely used with key applications including use as a polymer processing aid (increasing speed and reducing faults) and as an additive to lubricants, inks and coatings. This book is the only practical guide available to the selection and use of fluoropolymer additives, and will help readers to optimize existing fluoropolymer applications and implement new ones Fluoropolymers are known as an area where detailed information is hard to come by. In this book two former DuPont employees provide a wide range of industry sectors with the essential practical information and data they need to realize the full benefits of fluoropolymer additives Written for practicing engineers, Ebnesajjad and Morgan take a highly practical approach to the subject, based on real-world experience and case studies
