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.

Available in PDF, EPUB and Kindle. 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: In the past decades, the scan rate range of calorimeters has been extended tremendously at the high end, from approximately 10 up to 10 000 000 °C/s and more. The combination of various calorimeters and the newly-developed Fast Scanning Calorimeters (FSC) now span 11 orders of magnitude, by which many processes can be mimicked according to the time scale(s) of chemical and physical transitions occurring during cooling, heating and isothermal stays in case heat is exchanged. This not only opens new areas of research on polymers, metals, pharmaceuticals and all kinds of substances with respect to glass transition, crystallization and melting phenomena, it also enables in-depth study of metastability and reorganization of samples on an 1 to 1000 ng scale. In addition, FSC will become a crucial tool for understanding and optimization of processing methods at high speeds like injection molding. The book resembles the state-of-the art in Thermal Analysis & Calorimetry and is an excellent starting point for both experts and newcomers in the field.

Download or read book Plastics Additives written by G. Pritchard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although plastics are extremely successful commercially, they would never reach acceptable performance standards either in properties or processing without the incorporation of additives. With the inclusion of additives, plastics can be used in a variety of areas competing directly with other materials, but there are still many challenges to overcome. Some additives are severely restricted by legislation, others interfere with each other-in short their effectiveness varies with circumstances. Plastics Additives explains these issues in an alphabetical format making them easily accessible to readers, enabling them to find specific information on a specific topic. Each additive is the subject of one or more articles, providing a suffinct account of each given topic. An international group of experts in additive and polymer science, from many world class companies and institutes, explain the recent rapid changes in additive technology. They cover novel additives (scorch inhibitors, compatibilizers, surface-modified particulates etc.), the established varieties (antioxidants, biocides, antistatic agents, nucleating agents, fillers, fibres, impact modifiers, plasticizers) and many others, the articles also consider environmental concerns, interactions between additives and legislative change. With a quick reference guide and introductory articles that provide the non-specialist and newcomer with relevant information, this reference book is essential reading for anyone concerned with plastics and additives.

Download or read book Crystallization in Multiphase Polymer Systems written by Sabu Thomas and published by Elsevier. This book was released on 2017-09-15 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystallization in Multiphase Polymer Systems is the first book that explains in depth the crystallization behavior of multiphase polymer systems. Polymeric structures are more complex in nature than other material structures due to their significant structural disorder. Most of the polymers used today are semicrystalline, and the subject of crystallization is still one of the major issues relating to the performance of semicrystalline polymers in the modern polymer industry. The study of the crystallization processes, crystalline morphologies and other phase transitions is of great significance for the understanding the structure-property relationships of these systems. Crystallization in block copolymers, miscible blends, immiscible blends, and polymer composites and nanocomposites is thoroughly discussed and represents the core coverage of this book. The book critically analyzes the kinetics of nucleation and growth process of the crystalline phases in multi-component polymer systems in different length scales, from macro to nanoscale. Various experimental techniques used for the characterization of polymer crystallization process are discussed. Written by experts in the field of polymer crystallization, this book is a unique source and enables professionals and students to understand crystallization behavior in multiphase polymer systems such as block copolymers, polymer blends, composites and nanocomposites. Covers crystallization of multiphase polymer systems, including copolymers, blends and nanocomposites Features comprehensive, detailed information about the basic research, practical applications and new developments for these polymeric materials Analyzes the kinetics of nucleation and growth process of the crystalline phases in multi-component polymer systems in different length scales, from macro to nanoscale

Available in PDF, EPUB and Kindle. Book excerpt: In Beta Nucleation of Polypropylene, Dr. Philip Jacoby, one of the world's leading experts in the beta nucleation of polypropylene and its related applications, provides insight about the benefits of the material. The book thoroughly covers the required processing know-how to achieve these benefits, as well as fundamental knowledge of beta-nucleated polypropylene, nucleating agents, examples of applications, and a clear differentiation between the properties and design characteristics of conventional and beta-nucleated polypropylene. Beta-nucleated polypropylene has better strength and rigidity than conventional polypropylene, allowing for reduced weight and cost in applications and improved productivity through lowered cycle times. Applications include the automotive industry, electronics, packaging, household appliances, sport equipment, construction, textile, agriculture, and medical. This book discusses these applications in detail, showing how beta nucleation has been used to add value or produce a new product. It also addresses the influence of processing conditions on optimizing properties and performance.
