This book applies physical concepts related to research in elastomers/rubbers. The work aims to introduce and expound upon fundamental laws for understanding and subsequently controlling the shaping, fabrication, service performance and characterisation of elastomers and elastomer-related products. Rubber science has many important industrial and consumer applications such as tyres, isolators, seals, gaskets, hose, conveyor belts, cables, bushes, linings and many more. The mixing of rubber to meet the requirements for any given application is a complex and varied technique. Moreover, even a very simple rubber formulation may contain as many as 15 ingredients; each of these ingredients will have an essential role in controlling the properties of the end product. This book will provide to manufacturers and industrialists the fundamental knowledge for designing rubber formulations to meet the requirements of a diverse range of engineering applications.
