Book Description :

Despite mature applications, advanced technology, and high volume, rubber compounding has never had a book of its own. Today, emerging applications such as tire reclamation and smoke-resistant cables combine with an industry push into engineering materials to create new kinds of compounds with new quality control problems. The Mixing of Rubber has been developed over several years in conjunction with the Farrel Corp./Connecticut Rubber Group course to educate the hands-on compounder and the end user as well. It covers machinery, mixing, process control, quality control, plant operations and mixing advice for specific compounds. Like the course, the book assumes no prior knowledge of rubber compounding but leads the technologist through the process from mix procedure to test.

Book Description :

The production of rubber and rubber products is a large and diverse industry. The rubber product manufacturing industry is basically divided into two major sectors: tyre and non-tyre. The tyre sector produces all types of automotive and nonautomotive tyres whereas the non-tyre sector produces high technology and sophisticated products like conveyor belts , rubber seals etc. The wide range of rubber products manufactured by the rubber industry comprises all types of heavy duty earth moving tyres, auto tyres, tubes, automobile parts, footwear, beltings etc. The rubber industry has been growing tremendously over the years. The future of the rubber industry is tied to the global economy. Rapidly growing automotive sector in developing economies and increased demand for high-performance tyres are expected to contribute to the growth of the global industrial rubber market. The current scenario reveals that there is a tremendous scope for the development of rubber processing industries. The global market for industrial rubber products is projected to increase 5.8 % per year. Investment in rubber industry is expected to offer significant opportunities in the near future and realizing returns to investors willing to explore this sector. This book deals with all aspects of rubber processing; mixing, milling, extrusion and molding, reclaiming and manufacturing process of rubber products. The major contents of the book are rubbers materials and processing, mixing technology of rubber, techniques of vulcanization, rubber vulcanization, rubber compounding, rubber reclaiming, manufacture of rubber products, latex and foam rubber, silicone rubber, polybutadiene and polyisoprene, styrene butadiene rubber, rubber natural etc. The book contains addresses of plant & machinery suppliers with their Photographs. It will be a standard reference book for professionals, entrepreneurs, those studying and researching in this important area and others interested in the field of rubber processing technology.

Book Description :

The objectives of rubber compounding may be essentially defined as providing optimised performance and processability, generally at minimum cost, by the incorporation of non-rubber ingredients. Optimised performance in this context refers not only to mechanical properties but also, for example, resistance to bacteria or particular chemicals. In some applications a rubber may also need to be coloured, or bonded to another material, and further ingredients may be required. For many years, rubber compounding was largely empirical and frequently described as a black art. Today it is practised predominantly on the basis of scientific principles elucidated over years of study and is still the subject of intensive research. In this new report Claude Hepburn reviews the following range of compounding ingredients, considering the range of materials available, their particular actions and recent interesting advances: Process and extender oils; Process aids and surfactants; Coupling agents and adhesion promoters; Fire retardants, bactericides and blowing agents, colourants and odourants. An additional indexed section containing several hundred abstracts from the Polymer Library provides many more examples of novel materials and their applications.

Book Description :

Manufacturing rubber products requires the use of many additives. Therefore, mixing of the additives with the rubber is a very important step in the processing of rubber. There has been extensive research to try to understand the relationships between the formulation and the properties of the final product. In an industry with more than 100 years' accumulated history and a number of possible combinations of ingredients in the rubber formulation, there is an enormous amount of knowledge. However, this knowledge exists in fragments scattered as in-house 'know-how' among manufacturers and in the personal experience of the individual operators. This book organises this fragmented knowledge into a coherent whole based on scientific principles. This book is written for students, teachers and those in the rubber industry, who wish to acquire a scientific viewpoint of mixing. Last but not least it is written for the researchers in this field. With the latter in mind, subjects for future research are indicated wherever appropriate. With varied readers in mind, each chapter is written in such a way that it may be read independently from others.

Book Description :

Rubber compounding is a very complex endeavor. There are many interactions and many ways to achieve the target properties and economic goals while maintaining an acceptable trade-off for these characteristics. This book is dedicated to providing the reader with various experimental ideas which may guide him or her to developing better compounds and solving technical problems. In a combined effort, 20 reknown industrial esperts compiled a large number of diverse experimental suggestions for enhancing a specific compound property. By reviewing the suggestions in this book, the compounder may develop a better "feel" for how to best achieve a compromise or trade-off with compound properties when developing new or improving tested rubber recipes. Contents: - Introduction - Optimizing Cured Physical Properties - Improving Degradation Resistance for Cured Rubber Compounds - Optimizing Measurable Processability Properties - Minimizing Adverse Processing Attributes - How to Obtain Better Property Trade-Offs - Compatibility for Blends of Elastomers as Part of Vulcanizable Compounds - Typical Cure Packages for Compounds Based on Different Elastomer Base
