Thermoplastic elastomers (TPEs) have the elastic behaviour of rubber and the processability of thermoplastics. The Freedonia Group has forecast that demand will expand by 6.4% per year to around 2.15 million tons in 2006. There is potential for these new, exciting materials to expand into the much larger thermoset rubber markets. This review includes comparisons between the two material types. There are three major types of TPE: block copolymers, rubber/plastic blends and dynamically vulcanised rubber/plastic alloys known as thermoplastic vulcanisates. The chemistry of these materials and how.

The book provides a qualified and fast view into the world of TPE including the difference to rubber materials. It describes their classification as they are presented in the market, characterization, manufacturing, processing and behavior. Aside from the self-learning option, it is a companion to seminars and studies about elastomers.

Distinguishing among blends, alloys and other types of combinations, clarifying terminology and presenting data on new processes and materials, this work present up-to-date and effective compounding techniques for polymers. It offers extensive analyses on the challenging questions that surround miscibility, compatibility, dynamic processing, interaction/phase behaviour, and computer simulations for predicting behaviours of polymer mixture and interaction.

Science and Technology of Rubber covers the most important aspects of rubber science and technology, from synthesis and structure to elasticity and flow, blending, filling, and cross-linking. Polymerization and copolymerization, the rheological behavior of unvulcanized rubber, vulcanization, reinforcement of elastomers by particulate fillers, and the chemical modification of polymers are also discussed. This book is comprised of 14 chapters; the first ten of which take the reader from an introduction through synthesis characterization, mechanical behavior, and flow to the major processing steps of filling, compounding, and vulcanization and to the theories and measurement of elastomeric performance, leaning strongly on the ""materials"" approach. The next three chapters deal with blended, modified, and thermoplastic elastomers, touching on topics such as polymer esterification, etherification, hydrolysis, and hydrogenation as well as the influence of blending on the properties of elastomer/plastic blends, especially impact strength and crack resistance. The book concludes with a chapter on tire manufacture and engineering, with emphasis on the geometric, structural, and chemical aspects of tire. This book will be of vital interest to students, practitioners, and research and development managers, as well as to anyone interested in the unusual chemistry and physics and the outstanding properties and usefulness of elastomers.

The combination of its unique morphology, physical properties, cost effectiveness and environmental friendliness make natural rubber an appealing constituent for many materials and applications. This comprehensive two volume set covers the synthesis, characterization and applications of natural rubber based blends, interpenetrating polymer networks, composites and nanocomposites. Volume 1 covers different types of natural rubber-based blends and IPNs as well as manufacturing methods, thermo mechanical characterization techniques, life cycle analysis and their applications. Volume 2 focuses on natural rubber-based composites and Nanocomposites including the different types of fillers, the filler-matrix reinforcement mechanisms, manufacturing techniques, and applications. This is the first book to consolidate the current state of the art information on natural rubber based materials with contributions from established international experts in the field. The book provides a "one stop" reference resource for professionals, researchers, industrial practitioners, graduate students, and senior undergraduates in the fields of polymer science and engineering, materials science, surface science, bioengineering and chemical engineering.

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

A thermoplastic elastomer (TPE) is a unique polymeric material with properties and functional performance similar to those of a conventional vulcanized rubber; still it can be processed in a molten state as a thermoplastic polymer. The unique characteristics of TPEs make them very useful and attractive alternatives for conventional elastomers in a variety of markets, such as automotives, buildings and constructions, wires and cables etc. Thermoplastic vulcanizates (TPVs) are a special class of TPEs, produced by simultaneously mixing and crosslinking a rubber with a thermoplastic. TPVs based on PP/EPDM blends are the most important from a commercial viewpoint. When a peroxide is added as the crosslinking agent to a PP/EPDM blend, two competing processes take place simultaneously: EPDM crosslinking and PP degradation by chain scission. Therefore, there is a need for a proper peroxide in combination with a suitable co-agent to diminish the extent of PP degradation and improve the degree of EPDM crosslinking. The author addressed the understanding of the behaviour of various peroxides including multifunctional peroxides on the performance properties of the TPVs.
