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

Databook of Nucleating Agents gives engineers and materials scientists the information they need to increase the production rate, modify structure and morphology, and reduce haze of polymeric products with proper selection of nucleating agents and clarifying agents. Chemical origin and related properties of nucleating agents are analyzed in general terms to highlight the differences in their properties, including the essential theoretical knowledge required for correct selection and use of nucleating and clarifying agents. This includes methods of chemical modification of nucleating agents and their deposition on suitable substrates; methods, and results of dispersion of nucleating agents, influence of their concentration and cooling rate on final result and rate of crystallization, nucleation efficiency of different products and the reasons behind it, and generally accepted mechanisms of nucleation. The book also covers application aspects in different formulations. Patent literature and research papers are extensively reviewed for different applications, and polymer processing methods which require use of nucleating agents are discussed, with an emphasis on the intricacies of use of nucleating agents in different polymers and products.

Handbook of Foaming and Blowing Agents provides useful guidance to assist practitioners in the more efficient and effective selection of foaming methods and blowing agents. The book focuses on the selection of additives for a diverse range of foaming processes, which can be enhanced using modern chemical means to improve product quality, speed up the process, and broaden the range of products that can be produced using foaming technology. Foamed polymers have many beneficial properties, including lower density, high heat and sound insulation, and shock absorbency. Foamed plastic parts are now a ubiquitous part of everyday life—from food packaging to seat cushions. As the application of foamed polymers expands and diversifies, a variety of foaming techniques and equipment are available to produce very diverse range of products. Foaming methods are generally established, but very little is known about the composition of materials to be processed and the additives to enhance foam products or make the foam production more economical. The book introduces useful analytical techniques for foaming, and thoroughly discusses the environmental impact of foaming processes. - Introduces the fundamental mechanisms of action of blowing agents and foaming - Includes best practice guidance to help engineers and technicians improve the efficiency of their existing foaming processes - Enables practitioners to select blowing agents and foaming methods more effectively, reducing the risk of poor specification - Introduces useful analytical techniques for foaming - Discusses the environmental impact of foaming processes

Ever since the beginning of the plastics and rubber industry, it was realized that useful products could be produced only if cer tain additives were incorporated into polymers. With the help of these additives, when physically dispersed in a polymer matrix, it has been possible to improve stability against thermal, oxidative, UV, hydrolytic and biological degradation, mechanical properties, flammability, cost, and processibility of plastics. The enormous growth of the volume of plastics consumed by modern society, and new application areas for plastics, have created a demand for new, better additives and better understanding of their functions in polymer systems. As a result of these trends there is a need for sharing of information on progress achieved in the area of polymer additives among engineers and scientists of the plastics industry and academia. This book is based on expanded and updated papers originally presented at the International Symposium on Polymer Additives, which was held in Las Vegas, Nevada, and was sponsored by the American Chemical Society, Division of Polymeric Materials Science and Engi neering. The book is divided into five parts which cover advances in various areas of polymer additives. The first part is devoted to the progress in understanding of UV degradation and stabilization of various polymers. Oxidation degradation and stabilization of plastic materials is covered in the second part. New developments in the stabilization of PVC are presented in the third part.
