The scientific literature with respect to liquid silicone rubbers is collected in this monograph. The text focuses on the fundamental issues such as properties, curing methods, special materials, as well as the latest development and provides a broad overview of the materials used therein. In particular, materials and compositions for liquid functional rubbers are discussed. Also, methods of curing and special properties are described, such as tracking and erosion resistance, adhesion properties, storage and thermal stability. Methods of curing are precision casting, hybrid additive manufacturing, peroxide curing, ultraviolet curing, liquid injection molding, or hot embossing. The book includes applications including automotive and underwater applications, electrical and optical uses, as well as medical uses.
