Book excerpt: Handbook of Nucleating Agents, Second Edition gives engineers and materials scientists the information they need to increase the production rate, modify structure and morphology, improve mechanical performance, and reduce the haze of polymeric products through proper selection of nucleating agents (and/or the so-called clarifying agents). The book analyzes the existing literature paying special attention to recent developments, and is divided into 14 chapters, each of which concentrates on essential performances of nucleating agents. Chemical origin and related properties of nucleating agents are analyzed in general terms to highlight the differences in their properties and the book also provides the most essential theoretical knowledge required for proper selection and use of nucleating and clarifying agents. This includes polymer crystallization with and without nucleating agents, parameters of crystallization, essential influences on the nucleation processes, the measures of nucleation efficiency, the mechanisms of nucleation, and the effective methods of dispersion of nucleating agents. Later chapters concentrate on the application aspects in different formulations, outlining nineteen polymer processing methods which require use of nucleating agents, forty different polymers which are known to use nucleating agents, and sixteen applied examples of commercial products with nucleating agents. The final three chapters discuss the effects of nucleating agents on physical and mechanical properties of materials, the most essential analytical techniques, and health and safety in use of nucleating agents. Enables engineers to use nucleating agents more effectively to increase production rate, modify structure and morphology, and reduce haze of polymer products Provides a theoretical grounding required for proper selection and use of nucleating and clarifying agents Offers an extensive review of current applications of nucleating agents in different formulations Includes analysis of the chemical origin and related properties of nucleating agents to highlight differences in their properties

Available in PDF, EPUB and Kindle. Book excerpt: 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.

The 50+ chapters are written by some of the most experienced and prominent authors in the field, providing a truly unique view of polyethylene. The book starts with a historical discussion on how low density polyethylene was discovered and how it provided unique opportunities in the early days. New catalysts are presented and show how they created an expansion in available products including linear low density polyethylene, high density polyethylene, copolymers, and polyethylene produced from metallocene catalysts. With these different catalysts systems a wide range of structures are possible with an equally wide range of physical properties. Numerous types of additives are presented that include additives for the protection of the resin from the environment and processing, fillers, processing aids, anti-fogging agents, pigments, and flame retardants. Common processing methods including extrusion, blown film, cast film, injection molding, and thermoforming are presented along with some of the more specialized processing techniques such as rotational molding, fiber processing, pipe extrusion, reactive extrusion, wire and cable, and foaming processes. The business of polyethylene including markets, world capacity, and future prospects are detailed. This handbook provides the most current and complete technology assessments and business practices for polyethylene resins.

Available in PDF, EPUB and Kindle. Book excerpt: Both technically and economically, additives form a large and increasingly significant part of the polymer industry, both plastics and elastomers. Since the first edition of this book was published, there have been wide-ranging developments, covering chemistry and formulation of new and more efficient additive systems and the safer use of additives, both by processors in the factory and, in the wider field, as they affect the general public. This new edition follows the successful formula of its predecessor, it provides a comprehensive view of all types of additives, concentrating mainly on their technical aspects (chemistry/formulation, structure, function, main applications) with notes on the commercial background of each. The field has been expanded to include any substance that is added to a polymer to improve its use, so including reinforcing materials (such as glass fibre), carbon black and titanium dioxide. This is a book which has been planned for ease of use and the information is presented in a way which is appropriate to the users' needs.

Available in PDF, EPUB and Kindle. Book excerpt: This book extensively reviews Polypropylene (PP), the second most widely produced thermoplastic material, having been produced for over 60 years. Its synthesis, processing and application are still accompanied by vigorous R&D developments because the properties of PP are at the borderline between those of commodity and engineering thermoplastics. Readers are introduced to various tacticities and polymorphs of PP, and their effects on structural properties. Further, the book addresses the control of optical properties using nucleants, provides strategies for overcoming the limited cold/impact resistance of PP, examines in detail the effects of recycling, and presents guidelines for the property modification of PPs through foaming, filling and reinforcing with respect to target applications. Special attention is paid to descriptions and models of properties as a function of morphological variables. Last but not least, the book suggests potential practical applications of PP-based systems, especially in the packaging, appliances, building/construction, textile and automotive sectors. Each chapter, written by internationally respected scientists, reflects the current state-of-art in the respective field and offers a vital source of information for students, researchers and engineers interested in the morphology, properties, testing and modeling of PP and PP-based systems. The content is indispensable to the appropriate application of PPs and related composites.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Thermoplastic Elastomers, Second Edition presents a comprehensive working knowledge of thermoplastic elastomers (TPEs), providing an essential introduction for those learning the basics, but also detailed engineering data and best practice guidance for those already involved in polymerization, processing, and part manufacture. TPEs use short, cost-effective production cycles, with reduced energy consumption compared to other polymers, and are used in a range of industries including automotive, medical, construction and many more. This handbook provides all the practical information engineers need to successfully utilize this material group in their products, as well as the required knowledge to thoroughly ground themselves in the fundamental chemistry of TPEs. The data tables included in this book assist engineers and scientists in both selecting and processing the materials for a given product or application. In the second edition of this handbook, all chapters have been reviewed and updated. New polymers and applications have been added — particularly in the growing automotive and medical fields — and changes in chemistry and processing technology are covered. Provides essential knowledge of the chemistry, processing, properties, and applications for both new and established technical professionals in any industry utilizing TPEs Datasheets provide "at-a-glance" processing and technical information for a wide range of commercial TPEs and compounds, saving readers the need to contact suppliers Includes data on additional materials and applications, particularly in automotive and medical industries
